Apesar de hoje em dias as pessoas terem discos rígidos grandes, não custa nada retirar o que não está sendo usado, vi em um comentário e achei muito interessando o comando que apaga todos os kerneis antigos e deixa apenas o atual (ATENÇÃO SE VOCÊ NÃO SE SENTIR SEGURO NÃO EXECUTE).&lt;br /&gt;Indico usá-lo no seguinte caso, depois de atualizar o kernel mais novo, testar todas as funções, viu que não há problema com o novo kernel então execute o comando para remover os anteriores, caso haja uma falha, por exemplo, o som começou a não sair, a rede sem fio não funciona com o novo kernel não o execute, pois você ainda poderá fazer uso do  kernel anterior até que haja a correção no kernel atual.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;O comando é o seguinte:&lt;br /&gt;&lt;blockquote&gt;$  dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge&lt;/blockquote&gt;Caso dê algum problema ao copiar e colar reveja as aspas, pois às vezes o blog as modifica.Pronto, no meu caso foram-se três kerneis ficando só o mais novo.Copiado &lt;a href="http://andregondim.eti.br/ubuntu/removendo-kernel-antigo-com-um-comando/"&gt;daqui&lt;/a&gt;. Não sei se este blog estará online sempre, por isso copiei o artigo que eu mais consultava.&lt;br /&gt;&lt;br /&gt;Em memória de André Gondim.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1626506899435137936-2316904208047167746?l=blog.ayrtonaraujo.net' alt='' /&gt;&lt;/div&gt;&lt;img src="http://feeds.feedburner.com/~r/AyrtonAraujo/~4/gb-PE6NrEz8" height="1" width="1"/&gt;</content><link rel="replies" type="application/atom+xml" href="http://blog.ayrtonaraujo.net/feeds/2316904208047167746/comments/default" title="Postar comentários" /><link rel="replies" type="text/html" href="http://blog.ayrtonaraujo.net/2012/01/removendo-kernel-antigo-com-um-comando.html#comment-form" title="0 Comentários" /><link rel="edit" type="application/atom+xml" href="http://www.blogger.com/feeds/1626506899435137936/posts/default/2316904208047167746" /><link rel="self" type="application/atom+xml" href="http://www.blogger.com/feeds/1626506899435137936/posts/default/2316904208047167746" /><link rel="alternate" type="text/html" href="http://feedproxy.google.com/~r/AyrtonAraujo/~3/gb-PE6NrEz8/removendo-kernel-antigo-com-um-comando.html" title="Removendo Kernel antigo com um comando" /><author><name>Ayrton Araújo</name><uri>https://profiles.google.com/106755379005712728038</uri><email>noreply@blogger.com</email><gd:image rel="http://schemas.google.com/g/2005#thumbnail" width="32" height="32" src="//lh4.googleusercontent.com/-WzX5eoB9B2c/AAAAAAAAAAI/AAAAAAAAABU/D1a1H7RdU7c/s512-c/photo.jpg" /></author><thr:total>0</thr:total><feedburner:origLink>http://blog.ayrtonaraujo.net/2012/01/removendo-kernel-antigo-com-um-comando.html</feedburner:origLink></entry></feed>
