How To Subscribe To News using Thunderbird on Ubuntu

2026-02-27T23:11:00.000+07:00

Mozilla Thunderbird is the default email client application on Ubuntu. This powerful application has many features other than email management, and among them is, an RSS feed reader. That means an Ubuntu user can subscribe to any website and blog on the internet and the news will be ready to read every time he or she goes online. Isn't that amazing? Now we will explain it in a step-by-step manner as usual below based on our OS version 24.04 "Noble Numbat." Happy reading!

News Sources

We picked up some news sources here as examples for us to practice:

1. Ubuntu News, a company's news website

2. Distrowatch, a news aggregator and reviews of many other news websites

3. unixbhaskar.wordpress.com, an example of personal blog

****

Getting Started to RSS Feed URLs

What is RSS? RSS stands for really simple syndication, that is, a technology that allows Internet-based web news delivered automatically from the news source to the subscribers indicated by a symbol of an orange square. Nowadays, every website have a RSS feed for people to subscribe to.

(The RSS logo. Image source: Wikipedia.)

****

How To Subscribe to a News

1. Visit ubuntu.com website.

2. Find the RSS logo or link on the webpage. Here's some examples from the three sources above:

RSS logo on the bottom

RSS logo on the middle

RSS logo on the top

3. Right-click on the RSS logo or link -> Copy Link -> the link copied.

4. Run Thunderbird -> triple-line menu button -> New Account -> Feed.

5. On the Feed Account Wizard: click Next -> Finish.

6. Click the new entry "Blogs and News Feeds" in the left panel -> Manage Subscription.

7. Paste link from step number 3. It will look like this "https://ubuntu.com/blog/feed".

8. Click Add.

9. Subscription added. Done.

10. Repeat steps number 1-9 for Distrowatch and the WordPress.com blog.

****

How To Read a News

(Left: Blog & News Feeds selected. Middle: list of news. Right: news being read.)

Above is an example of a latest news from the Ubuntu blog titled "Unmasking Resolute Raccoon" that is planned to be released April this year. To read a news:

1. Click Blogs & News Feed section on the left panel.

2. Select a source you subscribed to. In this example, the "Ubuntu blog."

3. Select a news in the middle. In this example, the "Unmasking Resolute Raccoon."

4. The news will be viewed in the right panel. Done.

The default view mode is called Vertical View.

****

Switch to an Alternative View Mode

Above is an alternative view mode that puts the news content to the bottom instead of the right. This is called the Classic View. To enable it: click triple line button -> View -> Layout -> Classic.

Above is another alternative view mode that is similar to Classic but wider for the reader are to the bottom. This is called the Wide View. To enable it: click triple line button -> View -> Layout -> Wide.

Above is the full view. To enable it: double-click a news or right-click -> Open in new tab.

To revert back to the default view mode, select Vertical View instead under Layout menu.

How To Read Emails on Ubuntu using Thunderbird

2026-01-27T21:35:00.002+07:00

Mozilla Thunderbird is the preinstalled email client application on Ubuntu. Using this application, an Ubuntu user can read emails coming into his or her mail inbox. We will explain it in a step-by-step manner as usual based on our OS version 24.04 "Noble Numbat". Now let's learn and start the exercise!

1. Configure Thunderbird

If you have a Gmail account (or any email service other than Google), you should configure it first so Thunderbird can read your emails from the mail server. Please follow Thunderbird IMAP Setup Tutorial to do that.

****

2. Get started to Thunderbird user interface.

Here's how a Thunderbird window will look like on Ubuntu 24.04 "Noble Numbat."

(Green: the Header Bar part | Red: the main parts | Orange: statusbar)

It is divided into several parts:

top part aka "Header Bar" consists of a combination of (from right-to-left) three control buttons, three lines menu, a search bar, and a mode switcher button called "Mail". Note that this part is customizable on Thunderbird.

middle part consists of three columns, with the left column shows your accounts, middle column shows full list of your emails, and right column shows the content of a selected email. Note that this part is also customizable on Thunderbird.

bottom part consists of one horizontal panel called statusbar that will show a progress message following what Thunderbird is doing.

****

3. Where is your mailbox?

An inbox (also called mailbox) is a place where all your emails are stored under your email account. Where is your mailbox on Thunderbird? It is located right under your email address on the left sidebar. See for example our private email address below.

Once your Inbox is selected, the middle column will show the content of your inbox, that is, a full list of your emails sorted in an oldest-to-newest order by default. See picture below.

****

3. Read an email.

Click a mail title on the inbox area. The mail content will show on the right column by default. This is the default way you read an email on Thunderbird and it is customizable. Picture below shows an email from our subscription to Kubuntu Focus newsletter--one of our favorite GNU/Linux computer brands nowadays--.

An email consists of several parts:

subject: the title of the mail.

sender: the address of the person who sent the mail. *

recipient: the address of the person who receive the mail. *

date: the time when the mail arrived in the mailbox.

content: the full text content of the mail. Some mails also contains pictures. **

attachment: one or more files sent along with the mail.

*) May be hidden automatically to protect the users' privacy.

**) May be hidden automatically to secure the users from malicious codes.

3.1 Read an email in a new tab.

Want to view an email in full-width? Double-click a mail title (a subject) and the mail will be viewed on a larger space and this will open a new tab beside the Inbox tab. To go back, click the Inbox tab again.

****

4. Download an email attachment.

Many emails contain an attachment or two. What is it? It is a file that is attached to and send along with a mail. Mails which have attachments will show a paper clip symbol near its subject on Thunderbird (see below). Location of an attachment in a mail is at the bottom part of the content (see below).

(1) Which emails have an attachment?

See paper clip symbols on the most left column.

(2) Where is the attachment located on a mail?

See the bottom part of the mail content.

(This beautiful picture in PNG and XCF formats was sent by our sister Salsabila as an exercise in her computing course with us using GIMP)

(3) How to download an attachment?

Click a file listed on the attachment panel -> Save dialog will show -> Save.

(4) How to open an attachment?

Click a file listed on the attachment panel -> Open.

****

5. Sort emails.

Do you want to read emails easier and quicker? Sorting your mails can help you read them easier. We give you three examples below:

(1) Sort by date and the newest first.

Click the "Date" column header once or twice to sort your emails like this.

(2) Sort by subject and alphabetically.

Click the "Subject" column header to sort your emails from A to Z (and click it twice for a reverse order).

(3) Sort by attachment.

Click the "Paper Clip" column header to sort your emails by categorizing them between having and not having attachments.

Other ways of sorting can be enabled (or disabled) by selecting them on the "Select columns to display" button to the most right.

****

6. Search for an email in the inbox

Do you want to get an old mail in thousands of other mails? If you remember a key word of it, you can easily get it and read it again. To do so, first you should know there are two search boxes on Thunderbird:

(Green: top search box | Yellow: quick filter box)

top search box (green): type in here to search within all accounts (if there is more than one) on Thunderbird.

quick filter box (yellow): type in here to search only within one account. This will not search in the other mail account, if any.

If you want to search, you can do it like the following examples:

(1) Full search:

For example, we type the key board "computer" in the quick filter box and the following emails will show as the result. This is a full search, because all the four categories are enabled and it finds out whichever emails containing the word "computer" in the Sender, Recepients, Subject, and Body.

(2) Search by subject:

If we search for "computer" with only "Subject" category enabled, then only emails with the key word in the title will show like below:

(2) Search by sender:

If we want to find which emails whose the sender has the key word "computer", then we enable only "Sender" category and as a result, we found an email from an address containing "computer" in its name.

(3) Search by body:

If we want to find only the text content instead, we enable "Body" category and we found an example email containing the key word in one of its paragraph like example below.

Other ways of searching are still plenty you can do a little exercise to find anything you need.

****

7. Save an email

Open an email -> locate the group of buttons of Reply, Forward, etc. -> click More -> Save As -> Save -> the email will be saved as a file with a .eml extension. You can also choose other format namely HTML and Plain Text. See picture below.

****

8. Print an email or save it as PDF

Open an email -> click More -> Print -> select a printer from under "Destination: " (for example here our Canon PIXMA MP160) -> Print -> done. This will print out the email to physical papers. This requires a printer device to be connected and configured beforehand.

If you want to export it as PDF instead, do the same, but select Save to PDF under "Destination: " instead of a printer above, and Save. Done. You can read the exported PDF using Document Viewer.

That concludes this tutorial we humbly presented to you, dear readers of The Ubuntu Buzz. We hope this will help you a lot in practicing Ubuntu and Free Software in your computing life and others. We wish you success!

****

Acknowledgements

Thank you Mr. Rangga Ramadia--a knowledge seeker at our computer course in Indonesia--for being the inspiration for us to write this tutorial.

Thank you our beloved sister Salsabila Dwi Armadani--a young knowledge seeker at ours too--for always diligently sending an email after exercising with GIMP and LibreOffice.

We wish you all the best. Barakallahu feekum.

How To Install Debian 13 GNU/Linux "Trixie" with Dualboot Method, UEFI, and External Disk Storage

2026-01-16T17:41:00.001+07:00

This tutorial will explain detailed procedures to install Debian 13 GNU/Linux "Trixie" with GNOME graphical user interface into a PC or a laptop. You will be able to have Debian alongside other operating system with dualboot method. You will also be able to have Debian installed into either an internal hard disk drive or an external disk storage if you wish. Now, let's start reading!

(A message on the newly installed system says:
"Let's Begin. Learn about the key features in Debian GNU/Linux 13 (trixie)")

Requirements

A 64-bit computer or laptop.
An empty, GPT-formatted >= 8GB usb flash disk drive as a bootable medium.
An empty, GPT-formatted >= 32GB usb flash disk drive as a hard disk replacement, or,
An empty, GPT-formatted >= 32GB hard disk drive,
A RAM capacity of >= 2GB.
Patience, as the installation requires time, effort and electricity.

If you have no idea about this, we sincerely advise you to ask a person who has a good understanding and experiences in system installation to help you practicing this tutorial.

(Disk Utility showing a 32GB SanDisk CruzerBlade, GPT-formatted, located at /dev/sdb, with its full free space, which will be used as a hard disk drive replacement)

****

Download Debian 13 Live GNOME

We've got you a collection of full download links of Debian 13 "Trixie" below. To practice this tutorial, among many choices, you should grab Debian Live GNOME Edition. Just click this red button and download it.

****

Make a Debian Bootable

Use Disk Utility (Ubuntu) or Unetbootin (Windows and MacOS) program to write Debian image file into a USB flash drive as a bootable medium. This medium is required to install Debian into your computer. Click this button to learn about it.

****

Boot The Installer Up

1. Plug your Debian bootable USB in.

2. Turn the computer on.

3. Debian 13 will be displayed on screen like picture below. If not:

a. Then, reboot and immediately enter BIOS.

b. Set the BIOS so the computer will boot first to USB.

c. Press F10 (Save) and reboot from the BIOS.

4. On the Debian 13 menu (as shown in the picture), select the Live system option.

5. Debian 13 GNOME desktop live session will be ready.

Starting here, you will begin with the actual installation.

****

Step 1. Start the installer and select a language

Click the top-left corner of your screen and click Install Debian to the bottom. This will start the Debian GNU/Linux Installer like below. The first page should say "Welcome," and here select the language, American English, and then click Next.

Step 2. Select a timezone

On the Location page, select your Region and your City to determine your system's timezone. This will adjust your calendar, time, currency and numbering format following what your country is using. Then, click Next.

Step 3. Select a keyboard layout

On the third page, select English (US) or the default one. Then, click Next.

Step 4. Select the manual partitioning

On the fourth page, you will see a list of disks of your computer. This list will show both internal and external disk drives including those USB flash drives. Following the standard in this tutorial, as an example, we will install Debian Trixie into one of our SanDisk CruzerBlade 32GB flash drives located at /dev/sdb.

The rationale between this example is that if we are succeeded in installing Debian into a device as small as a flash drive, then you can do it too and even further, do it into any external disk drives.

You will create three (3) disk partitions namely EFI, swap, and root and then continue to the actual system installation.

A. Create an EFI partition

First, you should create an EFI partition by following an example below.

What is an EFI partition? It is a more or less 300MB-sized, FAT32-formatted, /boot/efi located partition in a disk drive required by the BIOS (now called UEFI) to boot the operating system. Without an EFI partition, your operating system will not boot up in a modern computer.

((1) Create from the free space: a new partition with (2) Size: 300MiB (3) File System: FAT32 (4) Mount point: /boot/efi (5) Flags: boot and finally click OK. An EFI partition will be created.)

B. Create a swap partition

Second, you should create a swap partition by following an example below.

What is a swap partition? It is a more or less 2000MB-sized, linuxswap-typed, swap-flagged partition needed by the GNU/Linux system. See annotated picture below.

((1) Create from the free space: a new partition with (2) Size: 2000MiB (3) File System: linuxswap (4) Flags: swap and finally click OK. A SWAP partition will be created.)

C. Create a root partition

Third, you should create a root partition by following an example below.

What is a root partition? It is the system partition where the whole Debian GNU/Linux system resides in a disk storage. It is called "root" because its path is the slash character ( / ) which is traditionally called "root" in the UNIX family. It is an EXT2-formatted, slash ( / ) pointed as the mount point, and sized as much as the free space left after making the two earlier partitions.

((1) Create from the free space: a new partition with (2) Size: <let it be as much as any capacity left> (3) File System: EXT2 (4) Mount point: the slash character (5) Flags: root and finally click OK. A ROOT partition will be created.)

Click Next to proceed to Step 5.

Step 5. Create a pair of username and password

You must have an account on your own system that consists of a pair of username and password. Here, feel free to create your username and password you will use with the Debian system.

Step 6. Evaluate the summary carefully

The system installer will show you a text summary of every configuration you have done so far. You must read this summary carefully and make sure everything is OK and nothing is wrong with it. Otherwise, you might not be careful enough to have your main hard disk drive wiped out (formatted) and that would be a disaster no one wanted.

Step 7. Start the actual system installation up and wait

If you are sure the summary is OK, click the Install button to start the installation. This installation of Debian 13 "Trixie" Live GNOME took about three (3) hours to finish on our system with the same setup (and that means four to six times longer than the previous release). Your result may vary depending on your hardware capabilities. While waiting for it, you can play with your children or sip a cup of coffee. Note: click Toggle log button to show up the messages of the actual installation progress being done in the background.

Step 8. Finish and restart

Once finished, the system installer will say "All Done" to you with a checked box saying "Restart now," and a Done button at the bottom. Click Done to begin the restart process. While it is processing to restart, unplug the bootable flash drive so only the Debian flash drive will still be plugged in.

Final Result

Once rebooted, your computer will boot into Debian 13 installed into the flash drive. It will say to you "Welcome to Debian GNU/Linux 13 (trixie)!" with a flying air baloon illustration. Congratulations! You have installed Debian into your computer successfully. Happy hacking!

Disks - An Intro to Ubuntu Default Disk Utility Application

2025-11-26T21:26:00.003+07:00

Disks, or GNOME Disk Utility, is the Ubuntu default disk storage management application. Its purpose is to manage everything about hard disk drives and other storage on your Ubuntu computer -- including optical discs (CDs, DVDs) and USB flash drives. That means you can alter the filesystem inside that disk (create, remove, resize, and rename it), format the disk (to MBR or GPT), make a backup, as well as write an ISO image to that disk, and do other useful things such as benchmarks and more configurations.

Description

Disks (GNOME Disk Utility) is the default disk management application on Ubuntu. It has a clean, consistent, and simple user interface with a left panel to show a list of disks and a right panel to show the details of a selected disk. Its purpose is to manage and change disk storage on an Ubuntu computer. That includes formatting the disks, manipulating filesystems on them, configuring various things such as automatic mounting, making backups and restoring, as well as benchmarking them. Furthermore, its purpose can be extended by combining it with the LiveCD ability of Ubuntu: Disks can also manage disk storage from other operating systems such as Microsoft Windows and Apple MacOS, even if those systems are present on other computers. Disks is an application originating from the GNOME Applications by The GNOME Project.

****

Purposes

1. View all disk storage on an Ubuntu computer, including:

Hard disk drive (HDD)
USB Flash Disk Drive (FDD)
CD Drive
DVD Drive
Solid State Drive (SSD)

2. Read detailed information from a disk or a filesystem, such as:

partition table (MBR or GPT),
unique identity (UUID),
type (EXT4, ReiserFS, Btrfs, FAT32, or NTFS),
size in GB,
and much more.

3. Formatting the disk with a partition table of choice:

Master Boot Record (MBR), or
GUID Partition Table (GPT)

4. Manipulate the filesystem inside a disk, including:

Creating
Removing
Resizing
Renaming
Reformatting the filesystem type (EXT4, FAT, etc.)

5. Imaging the disk, meaning two ways of:

Making a backup of the whole disk drive, resulting in an ISO image, and
Restoring a backup to a disk drive, and this also means

Writing an ISO Image file onto a disk drive to make a bootable medium

6. Making various configurations, including:

Shutting down a hard disk drive.
Enabling automatic mounting to a certain disk drive.
Making a certain disk drive read-only or fully writable.

7. Benchmarking a hard disk or a solid state drive (SSD), resulting in a chart and table of detailed information.

8. Testing the health of a hard disk drive via SMART data and self-test.

****

How To Run Disks

1. Click Ubuntu menu button.

2. Type "disks".

3. Click Disks logo.

2. Disks will detect and show it on the left panel. For example, "SanDisk CruzerBlade."

3. Select it.

4. Click the three-line button to the top > Format... > select MBR/MSDOS option > OK. Done.

****

C. Viewing a health measurement of a disk.

1. Select a disk from the left panel.

2. Click the three-line button to the top > SMART Data & Self-tests... >

3. Click Start > Short > type your password > wait for the process to take place.

4. When finished, it will show a message "Last self-test completed successfully". Done.

****

D. Benchmarking a disk.

1. Do the same like point C, but select Benchmark Disk... option instead.

2. Click Start Benchmark.

3. Click Start Benchmarking.

4. Type your password.

5. Wait for the process to take place.

6. While finished, a chart with detailed information will be shown. Done.

Disks can be launched via command line:

$ gnome-disks

Disks can also be called from Files (Ubuntu file manager) in several ways:

1. Right-click an ISO image file -> Open with Disk Image Mounter.

(This gives you similar functionality to popular but proprietary programs Daemon Tools and UltraISO.)

2. Right-click an ISO image file -> Open with -> Disk Image Writer.

(This gives you similar functionality to popular but proprietary programs Nero Burning [to CD/DVD] as well as AOMEI or UltraISO [to USB])

****

Location on the Screen and System

1. Disks can be found on Ubuntu applications menu.

2. Disks can also be found on Files (Ubuntu file manager) as mentioned above.

****

How To Run openSUSE Leap 16 on QEMU-KVM Virtual Machine

2025-10-09T00:03:00.003+07:00

This tutorial is inspired by errors and fixes we encountered when testing openSUSE Leap 16 yesterday. The problem is a kernel panic at boot time, so we cannot run it the same way we usually run other GNU/Linux operating systems up to today. After looking up and re-reading our old articles, we found out a solution. We hope you can run Leap 16 on a virtual machine quickly and easily with this. Now let's start reading and practicing!

(A QEMU virtual machine showing openSUSE bootloader with Install Leap 16.0 as an option highlighted in light green)

Identifying The Problem

We got a consistent error message saying, among all of them, "kernel panic - not syncing: Attempted to kill init! [...]" every time we run openSUSE Leap 16 virtually on our workstation Ubuntu 24.04 using QEMU-KVM virtual machine software. To be precise, we boot it up, openSUSE bootloader showing, we choose Install Leap 16, then boot up again and kernel panic. We used the same command line as with any other GNU/Linux image we have, while others worked successfully, only Leap 16 failed.

The command line used is:

$ sudo qemu-system-x86_64 -m 2G -cdrom Leap-16.0.iso

Meaning:

$ : the command is done in normal user mode.

sudo : the command asks to be done in super user mode for 15 minutes.

qemu-system-x86_64 : the actual command line of QEMU computer emulator. This version is intended for PC 64-bit aka x86_64.

-m 2G : we give 2GB as memory to this virtual machine.

-cdrom Leap-16.0.iso : we run QEMU in cdrom mode to read an ISO file.

(QEMU window showing a virtual machine running Leap 16 with a black screen, a lot of text message and a kernel panic)

****

Expected and Actual Result

It is expected that Leap 16 boots successfully and we should see "Installer" showing on screen with buttons we could click to proceed further.

However, actual result showing Leap 16 failed to boot with a black screen kernel panic message. No Installer, no further installation process we can do.

****

Identifying the Cause of Problem

After reading, we found out that openSUSE officially states that now Leap users should check their computer to meet the microarchitecture x86-64-v2 minimum requirement before using Leap. Otherwise, Leap will not boot nor work. To be clear, our old laptop ThinkPad T430 with Intel Core i5 Gen. III supports this requirement just fine. However, QEMU-KVM command line used above does not meet the requirement so the booting was failed.

(openSUSE Wiki web page X86-64 microarchitecture levels explaining this change happens and the reasons and a list of supported processors)

****

Running Leap 16 in Virtual Machine Correctly

We managed to boot openSUSE Leap 16 successfully in a QEMU-KVM virtual machine by changing the above command line into a new one below:

$ sudo qemu-system-x86_64 -enable-kvm -cpu host -smp 2 -m 2G -cdrom Leap-16.0.iso

Where:

-enable-kvm : enables Kernel Virtual Machine technology required by -cpu host option.

-cpu host : enables the physical CPU of our laptop to be the CPU of the virtual machine instead of a virtual one. This requires -enable-kvm option.

-smp 2 : (optional) gives 2 cores of CPU to this virtual machine simply to make the computing faster. The more the better as long as it doesn't slow down your host system. This is not required to solve our case.

(QEMU window showing a dark green openSUSE bootloader with a pointer selecting Install Leap 16.0 option with light green highlight)

(QEMU window showing openSUSE Leap 16 installer with two choices Leap 16.0 and openSUSE Leap Micro 6.2. To this point, it is a success!)

(QEMU window showing Leap 16.0 installer showing its first page Overview with the rest of page names visible to the left)

****

Conclusions

1. openSUSE Leap 16 now requires minimum computer microarchitecture to be x86-64-v2.

2. Simple QEMU command line ---like what we usually use--- do not work anymore with Leap 16. It leads to kernel panic.

3. -enable-kvm option is a must if we want to use our physical CPU to be the CPU for QEMU virtual machine.

4. -cpu host option is the solution to the above problem because it allows Leap 16 to run directly on our physical processor which already supports x86-64-v2. This option requires KVM features to be enabled.

Last but not least, we believe beyond this there should be other solutions. For the moment, this is the best we can share with everyone here. Thank you very much for reading!

How To Report A Bug You Found on Ubuntu with Examples

2025-10-02T08:13:00.000+07:00

Do you want to contribute to the community as an Ubuntu user? One of the simplest methods is by reporting a bug that occurs on your Ubuntu system if any. That way, the developers along with community can address and fix the issue to later they publish the fix as updates to the users. That's the origin of our daily software updates! We will explain it by examples and screenshots we hope you and everyone can follow easily. Now, let's read and try it!

Basic Knowledge

1. Reporting software bugs is a good contribution to our Free Software Community.

2. All Ubuntu bugs are located publicly at a central development website called Launchpad.

3. Ubuntu is already shipped with automatic bug reporter program called 'ubuntu-bug'.

****

Requirements

A Launchpad account. Please register if you don't have one.

****

Step 1. Run the problematic program

The first step is to know and make sure you have a program with an issue. You need to identify the name of that program to report it. Of course, you don't want to report a bug of GNOME Shell to KDE Plasma developer team (or vice versa) for example, as it would be a wrong report. You should report a bug of GNOME Shell to GNOME Shell developers. Or, you should report an issue with a program from Ubuntu to Ubuntu developers. The same is true to any other Free Software Projects. In this article, we give you two examples of our bug reports:

GNOME Notes (bijiben) crashes when running normally with default configuration on Ubuntu 24.04 Edit - submitted February 2025

xfce4-notes crashes after running for a minute on Ubuntu 24.04 - submitted August 2025

For your information, we found out these two bugs while writing our List of Ubuntu Desktop Notes Applications published last August.

****

Step 2. Run 'ubuntu-bug' Reporter

Then, run this special command line followed by the name of that problematic program. For example:

$ ubuntu-bug bijiben 

$ ubuntu-bug xfce4-notes

First command will report a bug with bijiben, while second one will report xfce4-notes. Like this, you can report any other bug you found out on Ubuntu.

****

Step 3. Fill in the bug report on web browser

Then, your web browser will show Launchpad web page form you need to fill in to report the particular issue. You should be already logged in to do so. For example, while reporting issue with bijiben, we filled in like the following:

Summary: "GNOME Notes (bijiben) crashes when running normally with default configuration on Ubuntu 24.04"

In what package did you find this bug?: "bijiben"

Bug description: "I run GNOME Notes (formerly Bijiben) on Ubuntu 24.04 until I can see the window but when I click New button, it automatically crashes (stopped working) without showing any message. ..." See full report here.

****

Step 4. Send bug report

Then, unless your bug report is about a security vulnerability, click Submit Bug Report button. Otherwise, give a check mark to "This bug is about security vulnerability".

Step 5. Your bug report will be published

Lastly, wait for your bug report to get responses from The Ubuntu Developers and community. Thank you for your report!

****

Example 1: Bijiben Crashes (Bug #2098611)

We reported a bug on GNOME Notes (aka Bijiben) which can be viewed here.

****

Example 2: xfce4-notes Crashes (Bug #2120475)

We reported a bug on xfce4-notes which can be viewed here.

FoxReplace - a Text Replacement Addon for Firefox Browser

2025-09-30T22:09:00.000+07:00

FoxReplace is a Firefox addon that is able to replace text in a web page, in both editing and reading mode, with or without regular expression (regex), both manually and automatically. We use it as a complement to Find and Replace which we reviewed last month because among both, only FoxReplace can do text replacing on Blogspot post editor. We need FoxReplace more because as you might have noticed already, this site --The Ubuntu Buzz-- is based on Blogspot. We hope this tutorial will help all other professional authors. Now let's start exercising like always!

How To Install FoxReplace

On Ubuntu version 24.04 with Mozilla Firefox version 143 and addon version 2.6.2:

1. Go to Mozilla Addons Org website.

2. Search for "foxreplace".

3. Select and install FoxReplace by Marc licensed under GNU GPL v3.

(FoxReplace official webpage at Addons Mozilla Org (aka AMO) website)

If you don't have an idea on these, please refer to our tutorial on installing a Firefox addon.

****

Basic Replacing a Text

We practice this on Blogspot (aka Blogger) post editor. Just like the last article, we copy Debian 13 "Trixie" announcement text here as sample text. We will replace the word "Debian" with "GNU/Linux" to see if it works.

1. Prepare sample text on Blogger text editor, for both title and content. See picture below:

2. Find the word "Debian" by pressing Ctrl+F then typing "debian" followed by ticking "Highlight All" option next to it.

3. All occurrences of the word "Debian" will be colored pink/magenta.

(Before replacing: original text says Debian as the name of project and system)

4. Click FoxReplace button -> Replace -> right sidebar will show "FoxReplace".

5. Type "Debian" into Replace and type "GNU/Linux" into With.

6. Click Replace.

7. All old text now replaced with new text, in both title and contents. It works! Done.

(After replacing: now GNU/Linux replaces Debian)

****

Fun Text Replacing on Your Favorite Webpages

One among purposes of FoxReplace is to do text replacements for fun. What does it mean? This means you can replace any text within your favorite website pages. This does no harm, because the changes only happen on your computer. As an example, let's try to apply the above exercise into Debian official webpage:

1. Visit Debian Trixie Announcement.

2. Do the above replacement.

3. All "Debian" will turn "GNU/Linux" on the entire webpages.

(Automatic text substitution happens on The Debian Project front webpage)

4. You can make substitution like this applied to all other websites by going to Options -> Add -> Substitutions -> fill in like the above to the table -> tick check mark to Apply automatic substitution on page load -> Save.

(Options page of FoxReplace showing an entry of our example substitution above)

5. Imagine fun things you can do with step 1 to 4 to any of your favorite websites.

****

Advanced Text Replacing with Regex

We present you here an example of advanced text replacing using regular expression (regex). We will automatically remove all numbers, one digit or more, followed by a period and a white space, in the beginning of every line. Think about it if you have a very long list of names with number while you want just the text list and not the numbers.

1. Copy a short numbered list below into Blogger post editor:

1. Apache 2.4.64
2. Bash 5.2.37
3. BIND DNS Server 9.20
4. Cryptsetup 2.7
5. curl/libcurl 8.14.1
6. Emacs 30.1
7. Exim (default email server) 4.98
8. GNUcash 5.10
9. GNU Compiler Collection 14.2
10. GIMP 3.0.4

2. Open FoxReplace sidebar.

(Before replacing: a sample text)

3. Type "^[0-9]+\.." correctly without quotes into Replace.

4. Click Text option and select Regular Expression.

5. Empty the With input box.

6. Click Replace.

7. All occurrences of number in beginning of every line will disappear. Wonderful! Done.

(After replacing: resulting text is now clear from unnecessary line numbers)

****

About FoxReplace

FoxReplace is a Firefox addon that helps the user to substitute text in all web pages, in both editing and non-editing areas, with or without regular expression (regex). The developer of this addon is Marc, the source code is available at GitHub and it is a free software licensed under GNU GPL. There is no donation opened by the project, but if you want to contribute you can rate it on its official webpage or join the development on GitHub. Its official webpage is at AMO/FoxReplace.

How To Use Transmission BitTorrent Application

2025-09-30T00:20:00.003+07:00

Transmission is a download and upload manager application or technically called a BitTorrent client preinstalled on Ubuntu. It is one among a few Ubuntu default applications with a longest history and never had been replaced with any other along with Firefox and LibreOffice. In this tutorial, we will learn about using Transmission to download a torrent file from the internet by practices and examples. Now let's get going!

(Transmission running and showing a progress of downloading a torrent, other finished downloads and its program identity on the second window)

Why BitTorrent?

No server, but Peer To Peer - BitTorrent method is an alternative to standard downloading "click Save As on the web" or also known as HTTP.

Very fast - Mostly or always faster than standard downloading.

Very reliable - When download failed, you only need to repeat from the point where it failed, not repeating back from zero percent again.

Resumable - Pause a download today, resume it next month or next year is okay with torrents.

Automatic checking - When download finished, you can be sure the file is 100% intact.

Repairing - If a file you got from standard downloading is corrupted, you can repair it by using torrent.

Aligned with the community spirit - The free software community (within it there are Ubuntu, Debian and others) always shares ISO images and other large files via torrents. By uploading (seeding) files you downloaded, you are contributing to the whole community and that's a good thing.

Abundant - Most digital files are available via torrents regardless of copyright and licenses and they can be obtained very easily. Other than GNU/Linux images, there are collections of photos/pictures, movies, audio recordings, books, magazines, software and video games etc.

****

Before Downloading

Please consider things below:

1. In general, files you can download via torrent are very large (usually more than 1GB) except a few ones of them so make sure you have enough free disk space before proceeding.

2. Beware of downloading (and automatically sharing) files covered with copyright and/or nonfree licenses. These are known to be subject of dispute and enmity among people. You are responsible to your own decisions.

3. Be careful of your internet bandwidth and surrounding. Downloading a torrent can be very fast and resource demanding to your local network. Stop or close Transmission once a download finished, otherwise you will automatically upload same size you download or more unnoticed (unless you decided to contribute to the community by seeding). Limit download speed and decrease peers if you do this on a public place, let's say, like a cafe, otherwise you might disrupt other people using the same network.

****

Let's start the exercise below:

Below is an example of two torrent files viewed on Ubuntu. The first one is named mushafabdullahalmatrood_archive.torrent sized around 40KB. This file can be used to download several first chapters of Al Quran recitation in ten MP3 files by total size of 1.6GB. The second one is named ubuntu-24.04.3-desktop-amd64.iso.torrent by total size of around 400KB. This file can be used to download Ubuntu operating system by size of 3GB. Please note that the actual files are typically large, but the torrent files are always small. These are actually just a file containing information pointing to the original files to be downloaded and list of tracker servers will be used to proceed the download. This kind of files are called torrent files or simply torrents.

****

Get a Torrent File

If you don't have a torrent file yet, then you should get it first to proceed. We picked here two examples to exercise:

1. ubuntu-24.04.3-desktop-amd64.iso.torrent (400KB)

2. mushafabdullahalmatrood_archive.torrent (40KB)

To get torrent number 1, go to Ubuntu Official Website and pick Alternative Downloads, you will find BitTorrent links available there. This torrent file points to a 6.5GB Ubuntu ISO image file. This is also true for any other GNU/Linux operating systems and beyond.

To get torrent number 2, go to this [Ten Chapters of Quran] Abdullah Almatrood web page, and click TORRENT link. This torrent file points to a 1.6GB archive of MP3 files. This is also true to any other millions of downloadable files available on the Internet Archive.

****

Download a Torrent File using Transmission

Example 1: Downloading Ubuntu

1. Run Transmission.

2. Click File -> Open -> Open File will show.

3. Navigate to your file ubuntu-24.04.3-desktop-amd64.iso.torrent (400KB) -> Open.

4. Torrent Options will show like the following:

a) the torrent file (ubuntu-24.04.3-desktop-amd64.iso.torrent here)

b) the directory to save the actual file (Downloads here)

c) disk space information (12GB free here)

d) list of actual file will be downloaded (Ubuntu Noble Numbat 6.5GB here, checked)

e) Cancel and Open buttons at the bottom.

5. Change the destination directory if you wish (for example, we always save actual ISO files in a secondary hard disk drive).

6. Click Open.

7. Download will start.

Special: in torrents, when downloading you will see number of peers and number of trackers. Peers are people who are currently downloading the same file as yours. Trackers are not a central server (unlike in standard HTTP downloads) but servers that track (note, record) peers who have the same files to let you download from them directly. This is a very simplified explanation. To learn more, please read References section below.

8. Once finished, Transmission will color the progress bar green and show a message "Seeding to x of x connected peers". As a result, you got a Ubuntu 24.04.3 image by 6GB size. Done.

****

Example 2: Downloading Al Quran Recitation

1. Redo the Example 1 for 2. mushafabdullahalmatrood_archive.torrent (40KB)

2. Torrent Options will show a slight difference like below:

Contents of this torrent:

a) "mushafabdullahalmatrood" directory

b) "001-alfatiha.mp3" (1MB) up to "010-yunus.mp3" (30MB) files.

c) "001-alfatiha.ogg" up to "010-yunus.ogg" and other types of files.

3. Select which one of the files you want to download. For example, picture above showing we only select one file "Al Fatihah MP3" to be downloaded.

4. Click Open and Transmission will download like explained above. As a result, you got a folder named mushafabdullahalmatrood and in it a file named 001-alfatiha.mp3. Done.

****

Limiting Speed and Peers

1. Right-click a running torrent.

2. Select Properties -> Options.

3. Under Speed, tick Limit download speed.

4. Fill in it 100 to limit it by 100 kilobytes per second (KB/s), for example. Please adjust the number wisely. (Note: do the same if you want to limit Upload Speed)

5. Under Peer Connections, change 50 to 3 to limit peers to just three persons, for example. Please adjust the number wisely too.

6. You can limit either one of these two, or both. By doing these, your transfer might become slower, but your burden to the network will become lighter. Done.

****

Stopping a Torrent

1. Select a running torrent, either it is downloading or uploading (seeding).

2. Click Pause button.

3. Torrent transfer is stopped until Start button clicked. Done.

****

Delete a Torrent

1. Right-click a torrent, whether it is running or already stopped.

2. Remove Torrent (Delete).

4. A message window will show a question "Remove torrent?"

5. Click Remove once again.

6. Torrent removed from Transmission. However, this only deletes the entry, while the saved folder and file are safe and not deleted. Usually, this does not free much disk space.

7. Alternatively, to delete a torrent along with its files, select Delete Files and Remove (Shift+Delete) instead in step 1. Usually, this frees much disk space.

****

Viewing Peers

As mentioned above, Peers are People who are currently downloading (or uploading) the same files as yours. You can view list of them like the following.

1. Right-click a running torrent.

2. Select Properties -> Peers.

3. Properties window will show a detailed list of peers of selected torrent:

a) Up: whether peer is doing upload or not to you.

b) Down: whether peer is doing download or not to you.

c) %: percentage of data transfer by this peer.

d) Flags: particular information about methods being used by this peer.

e) Address: IPv6 or IPv4 address of this peer.

f) Client: software being used by this peer to run this torrent. Examples here include Transmission, Deluge and qBitTorrent.

4. Close Properties window. Done.

****

Viewing Trackers

Now, how does Transmission find peers? Because there are trackers, special servers on the internet helping us find peers* so we can download the file directly from those peers simultaneously. To view trackers:

1. Right-click a running torrent.

2. Select Properties -> Trackers.

3. Properties window will show a detailed list of trackers of selected torrent:

a) torrent.ubuntu.com is a tracker server provided by The Ubuntu Project for humanity.

b) ipv6.torrent.ubuntu.com is the same but provided for IPv6 users worldwide.

c) First tracker gave us 6 peers, while second one gave us 1 peer.

d) Add, Edit, Remove buttons are useful. Trackers can be added to help ourselves find more trackers (usually to increase peers that in turn can increase download speed) or remove unused one.

There are many other tracker servers in the world.

*) Note: aside from an ability called DHT to do that even without trackers.

****

About Transmission

Transmission is a BitTorrent client software that is free software (GNU GPL licensed) and has a long history being chosen and trusted as Ubuntu default download manager. Transmission main purpose is for file sharing, for both peer to peer (P2P) file upload and download via an internet protocol called BitTorrent, and thanks to that, Transmission can be used to download (and upload) in high speed large files like collections of audio recordings, videos, digital books, magazine, documents, photos, software etc. Technically, Transmission is written in C++ with two choices of user interface, GTK and Qt, developed in public at GitHub by the community who invites everyone to join in. Its development is funded by donation and if you want to donate to the project, you can send it to the link in the References section.

2025-09-28T23:25:00.000+07:00

Elisa is Kubuntu default audio player. In Kubuntu history, Elisa replaces the former players namely Cantata and Amarok. Elisa is a part of KDE Applications and well integrated to the KDE Plasma Desktop. Speaking about its appearance, its logo represents a black-green tape cassette and its user interface reminds us to the old three-columns style Amarok. Speaking about its technical aspects, it is written in C++ with Qt Framework, just like any standard Kubuntu application, developed in public by the KDE community. Just like what we have discussed at the previous episode, Dolphin File Manager, we will also explain Elisa in details with screenshots and further references. We hope this helps every Kubuntu users. Now let's start reading!

Collection of Ubuntu 24.04 Tutorials Part II: CHM, AppImages, Telegram and Synaptic

2025-09-26T22:06:00.000+07:00

This is the second compilation of our Ubuntu 24.04 Noble Numbat tutorials which have been published here at The Ubuntu Buzz since 2024. In last compilation, we talked about downloading Ubuntu up to selecting our repository server among others. In this episode, we will remind you about CHM ebooks, AppImages, Telegram Desktop as well as the classic but powerful Synaptic Package Manager with a short review for each. We hope this compilation series will be useful to you and everyone. This marks our last article of that year in the month May. Please enjoy!

(Telegram Desktop running peacefully showing KDE Channel on Ubuntu Noble)

In this compilation:

1. How To Read CHM E-Books

2. How To Run AppImages with Examples

3. How To Install Telegram Desktop - The New Era of Messaging

4. How To Install Synaptic - The Classic but More Detailed Graphical Package Manager

5. How To Use Synaptic to Search, View, Install, Remove, Update Apps on Ubuntu

****

How To Read CHM (Compiled HTML) eBooks

Let us introduce you xCHM: a free software for viewing Compiled HTML aka CHM electronic books. If you have a file with a .chm format, you can view its content with it. This beneficial and useful is available on Ubuntu 24.04.

How To Run AppImages

AppImage is an executable software format for GNU/Linux (similar to EXE is an executable format for Microsoft Windows) which fortunately today got many support from free software developers around GNU/Linux community. For example, today almost all of our daily applications are already available in AppImage format such as GIMP (recently), Inkscape, and LibreOffice among many others (and still increasing!). This means we can, let's say, visit GIMP official website to download its AppImage file then run it on Ubuntu in an instant way similar to those applications on Windows or macOS.

Telegram Desktop

This will help you install the full-featured, fast messenger Telegram Desktop. Enjoy the new era of messaging on Ubuntu!

Synaptic Package Manager

Once upon a time, Ubuntu had a very powerful, highly-detailed graphical package manager called Synaptic as one of its preinstalled applications. Its purpose is to search, view categorized & detailed info, install, reinstall, remove, update packages and the whole system on Ubuntu. It was able to show all Ubuntu packages at once, both installed and not, with more detailed info or specific filters can be applied/viewed simply by near clicks. However, Synaptic had been removed from Ubuntu preinstalled in favor of App Store. To get Synaptic back, we can install it again.

Using Synaptic: Install, Remove and Update Your Applications with More Details

In this tutorial, we explain how you can use Synaptic to do package management in a short step by step manner with practical examples and exercises. This marks the end of Part II. Please go read it!

How To Upgrade Ubuntu 24.04 to a Higher Point Release with Command Lines

2025-09-08T23:12:00.003+07:00

Do you want to upgrade Ubuntu Noble Numbat from 24.04 to 24.04.1 or later? If so, then that means you are looking for how to upgrade Ubuntu system to a point release. The term "Point Release" to Ubuntu users is more or less similar to "Service Pack" known to Microsoft Windows users which is a whole system upgrade (bug fixes and improvements) within current release major version. That means, in this concept, to us Ubuntu 24.04.3 (Point Three) is more or less similar to Windows XP SP3. This tutorial will explain the procedures with an example of upgrading Ubuntu Noble from fresh install to Point Three.

Preparations

1. Make sure you have enough time and free disk space.

You will need to attend in front of your screen for about 2 hours (time needed depends on your system). To check up your disk space, run Terminal from Ubuntu menu and type this command line:

$ df -h /

If you have 10GB or more free disk space (in our test, we have more than 15GB), you are ready to upgrade. Beware of running out of disk space because you might break your system if you do.

2. Make sure you have a good internet access (good speed, good data allowance, good stability).

For example, we use a broadband 5MB/s unlimited internet access at home (MyRepublic ISP, Indonesia) to do this upgrade process and we did it successfully.

3. Make sure you have a stable electricity.

You will not want the upgrade process to abort in the middle (that might leads to breaking your system).

****

How To Upgrade

All command lines are done using Terminal application you can run from Ubuntu menu.

1. Do the first command:

$ sudo apt-get update

Explanation: this command line will refresh Ubuntu to know the latest changes available in the Ubuntu repository to make the system ready to upgrade.

2. Do the second command:

$ sudo apt-get upgrade

Explanation: this command line will actually do the upgrade process. That means, downloading latest version of every single package of thousands of packages installed on your Ubuntu version and installing them one by one in a correct and orderly way replacing the old ones. In our test, this took 1000MB (1GB) of software packages and 100MB disk space.

3. Do the third command:

$ sudo apt-get dist-upgrade

Explanation: this command line will do the same with the second command. The difference is, the second command does nothing except installing (adding) packages while this third command will also remove (deleting) packages when needed i.e. it is an automatic package conflicts solver. In our test, this took about 260MB of download size and 400MB of disk space.

4. If prompted to reboot, accept it by clicking Restart Now. Your computer will reboot.

5. Login to Ubuntu and check current system point release. Upgrading finished successfully. Done.

****

Important Information

1. You might need to repeat an upgrade command several times (when somehow an error occurred) as we did. This is fine.

2. You can use -V option (as we always do) in both upgrade commands to show in details every single one of packages being upgraded from what version to what version.

3. You can use $ sudo apt-get clean to empty the APT cache directory to free some disk space.

Find and Replace - a Firefox Addon So Useful for Online Text Editing

2025-08-31T14:08:00.000+07:00

Find and Replace for Text Editing (or simply Find and Replace) is a Firefox addon to do what its name says by Blake Altice (originally written by Dalimil Hajek). It has capabilities to find text based on regular expression (regex) as well as simple plain text. It also has other features such as Favorites, History, Templates and Help coming as a full package. Now we want to explore it with examples we found to do simple text replacements. Enjoy!

Usage Examples

We found that Find and Replace works in these examples:

Web email editing: This includes your webmail Gmail, Yahoo!, Mailo, Protonmail etc.

Wikipedia editing: This includes Wikipedia as well as other wiki websites.

WordPress editing: This includes WordPress but excludes Blogspot.

GitHub and Comments editing: This includes many plain-text comment editors available on almost all websites nowadays including Issues in code forge websites such as Codeberg, Launchpad, GitLab alike.

Pastebin and online text editors: this includes Pastebin alike as well as other web-based text editors such as Online Pad.

Etherpad and collaborative text editors: this includes Etherpad (with some notes below) and alike.

****

How To Install Find and Replace

On Ubuntu version 24.04 with Mozilla Firefox version 142 and addon version 1.3.18:

1. Go to Mozilla Addons Org website.

2. Search for "find and replace".

3. Select and install Find and Replace by Blake Altice.

If you don't have an idea on these, please refer to our tutorial on installing a Firefox addon.

****

How To Find and Replace Some Text (Wikipedia)

The best way to know Find and Replace features is to try it out editing a Wikipedia page without saving it. We picked here Debian page. The goal is to replace the phrase "Linux distribution" to "GNU/Linux distribution".

1. Visit https://wikipedia.org/wiki/Debian.

2. Click Edit.

3. Click within the text editor.

4. Click Find and Replace logo or press Ctrl+Shift+F to show its user interface.

5. Type "Linux distribution" in the first text box to find all matches (will be colored in orange and blue).

6. Type "GNU/Linux distribution" in the second one.

7. Click Replace All to replace them all at once, or, click Replace to replace them one by one. Done.

****

Web email example

We picked Mailo Web Email here and copied Debian 13 "Trixie" release announcement [1] as the text to replace. No extra tricks needed. It works.

****

WordPress example

We can confirm that Find and Replace works on both Classic and the modern Block Editors. We used Debian Trixie announcement [1] again here. (Note: unfortunately, we can also confirm that it doesn't work with Blogspot at all). It works!

****

Comments example

We picked WordPress Comments section here. It works like in the post editor. It works!

****

Online text editor example

We have tried text editors based on TinyMCE (the one everyone knows as WordPress Classic Editor) as well as others which are simple enough to edit plain text (meaning, less JavaScript). We used Debian Trixie announcement [1] again here. It works with TinyMCE!

****

Pastebin example

We tried out Pastebin and it is a success for Find and Replace. We used Debian Trixie announcement [1] again here. It works.

****

Etherpad example

It almost does not work on Etherpad until we found a little "trick" to make it work. It might be not comfortable for most users.

The trick is:

1. Do the steps above until step number 5.

2. Watch the matching colors appearing, they will quickly disappear.

3. Click either one of buttons under two input boxes (e.g. Match Case or Advanced Options).

4. Click Replace or Replace All as long as all matching colors are still appearing.

5. Do steps number 3 and 4 quickly, otherwise one or some matches will not be replaced. Done.

****

GitHub example

We picked GitHub here as an example and this should also works on other web code forges Launchpad, GitLab, Codeberg (Forgejo), Sourceforge etc. What is this? This is the place where people come to develop software together and people who found an issue report that issue to the developers.

****

Forum example

We picked Ubuntu Forum (discourse.ubuntu.com) here to test it out. It works.

****

Caveats

1. We can confirm that it does not work with Blogspot.

2. It does not work on W3Schools text editor.

3. It does not work on Hedgedoc markdown editor (formerly CodiMD).

4. It does not work on CryptPad text editor as well as its OnlyOffice.

We hope next versions of Find and Replace will fix these issues. Thank you Blake Altice and Dalimil Hajek.

****

About Find and Replace

Find and Replace is a Firefox addon that helps the user to find a certain text in a text editing area in the browser, and replace that text with other text as the user wishes, with or without regular expression (regex). The original developer of this addon is Dalimil Hajek, the source code is available at GitHub, and he wrote his 2018 dissertation report at University of Edinburgh based on it. However, the repository is now marked as "archived" and the project has been taken over by other developers (but we cannot confirm who were they it yet). On the Mozilla Addons page, the name of the developer is now Blake Altice (but we also cannot make sure who is he as the link is still pointed to Dalimil Hajek) and the license is mentioned as Mozilla Public License. Last but not the least, the donation to this project can still be sent to Dalimil Hajek.

List of Desktop Notes Applications on Ubuntu 24.04

2025-08-12T23:42:00.000+07:00

This listing collects desktop notes applications including sticky notes that we recommend for Ubuntu 24.04 Noble Numbat. We included here KNotes, which are well-known and full-featured, and also Affiche.app which just works but less-known, among others in order to promote them to more users (and open the opportunity for more people to get involved in the project). All applications are available in the official repository and no third-party sources required. Now, let's start exploring them!

Affiche.app
Gnote
Knotes
GNOME Notes (Bijiben)
XFCE4 Notes
Rhinote
Tomboy NG
Zim Desktop Wiki

Affiche.app

Affiche.app is a note taking application from GNUStep. Once installed, you run the program by a special command line $ openapp Affiche.app (notice that it is case-sensitive) and it will run. It works fine on Ubuntu GNOME the same way any other GNUStep application works. Official website.

Gnote

Gnote (not to be confused with GNOME Notes) is one of two successors to the original GNOME notes taking application called Tomboy which is now discontinued. The difference is that Gnote is written in C++ while Tomboy is written in C# (with Mono Framework). Features including basic note taking and linking between notes. Unique part of it is, among others, it does not appear as sticky notes but more of plain text editor. Official website.

GNOME Notes

Notes (formerly Bijiben, first released 2012) is a sticky note application from GNOME, the desktop environment technology that builds Ubuntu. Features including basic note taking as well as ability to read notes created by other GNOME note taking application. However, when we run it, the window appears but when we want to create one, the application crashes and this is an already-known case (see bug report above). We hope this issue will be fixed soon. Official webpage.

KNotes

KNotes is a sticky note application from KDE, the desktop environment technology that builds Kubuntu. KNotes, even though it is a KDE application, can be installed and run on Ubuntu GNOME just fine. Once started, it will show on the top panel (system tray). On first launch, you will be asked about which folder to save the notes, then under "Notes" create a new folder named "KNotes" then below it make sure the selected folder is pointing to "Notes/KNotes". Use "Show All Notes" to view notes you have made. Features including basic note taking, basic text formatting, and colors. Its looks resemble real sticky notes. Official website.

Rhinote

Rhinote is a small but fast, handy, keyboard-friendly program that provides virtual sticky notes. It is simple enough to run as a small window without any menu or toolbar, without system tray functionality too. Because it is designed to hold down quickly your temporary text whenever you need, it does not automatically save your notes so when it is closed, all unsaved text will lose. To use it, one beautiful advice is to press Ctrl+H to show its list of commands useful for you. Official website.

Tomboy NG

Tomboy NG (New Generation) is the successor to the classic Tomboy Notes other than Gnote. Speaking about comparison, while Gnote is written in C++, Tomboy NG is written in Pascal programming language instead. Features including basic note taking, linking between notes, text formatting, menu, system tray icon, even exporting as PDF and many others. It works well! Official website (GitHub).

XFCE4 Notes

Xfce4 Notes is a sticky note application from Xfce, the desktop environment technology that builds Xubuntu. It is simple enough to give a yellow note on desktop with icon on its top-left corner as a clickable menu to access more functionalities. However, unfortunately we found it crashes when running for a while so we lost all text written on it every time we started it. We reported it to Ubuntu Developers (see above) and we hoped that this issue will be solved soon. Official webpage.

Xpad

Xpad is a simple sticky notes application from GNOME (not to be confused with XApps from The Linux Mint Project) written in its standard language C/GTK+. It works with its basic note taking features, basic text formatting, color scheme and configurations. Official webpage.

Zim

Zim is a note taking application in Wiki style and powered with its own web server. Meaning, you can create memos just fine but as an addition, you can make your memos interlinked with each others and you can browse it as a local website using your web browser. To try it out, simply open the Help which also written in Zim own style and go to Tools -> Start web server -> Start. Interesting, isn't it? Features including basic note taking, text formatting, inserting images, using templates and is extensible via plugins. Official website.

How To Install Tux Typing Game on Ubuntu 24.04

2025-08-06T00:07:00.000+07:00

Tux Typing (or tuxtype) is free software education game designed for kids to learn keyboard typing and English vocabularies by playing. As part of The Tux4Kids Project, Tux Typing is a sibling to Tux Math, a similar education game but for studying mathematics. All in all, let's start enjoying it!

How To Install Tux Typing

1. Click Ubuntu menu button.

2. Find Terminal and run it.

3. Type the following command lines then press Enter. You will need to type your password to proceed.

$ sudo snap install tuxtype

4. Type this second command line then press Enter:

$ sudo snap connect tuxtype:alsa

5. Tux Typing is installed successfully. Done.

****

How To Run

1. Click Ubuntu menu button.

2. Find Tux Typing and run it.

3. Tux Typing runs. Done.

****

How To Play

1. Run Tux Typing.

2. Tux Typing window will show. Select Fish Cascade option.

(Front page of Tux Typing)

3. Select a difficulty level. Here we pick Easy.

(Difficulty level selection)

4. Select a lesson. Here we pick Animals.

(Lesson selection)

5. Game starts! Type every animal name coming down slowly as as fishes so Tux the penguin can eat them all and your score increases. However, if you missed one, Tux will lose one life. When Tux loses all his lives, you lose. Have fun!

(Playing!)

6. You can try other options from 2, 3 and 4 to find more games. Done.

****

Caveats and How To Remove

The installation above is done from Snapcraft in form of Snap package, not the traditional Debian DEB package. However, we noticed that the DEB installation introduces the same issue as Tux Math we have explained in the previous episode. If you want the traditional package instead of Snap, use this command line:

$ sudo apt-get install tuxtype

To uninstall the game, pick one of these commands:

$ sudo snap remove tuxtyping
$ sudo apt-get remove tuxtype

Done.
