Como posso remover os kernels antigos / instalar novos quando o / boot está cheio?

Eu sei que essa pergunta é feita muitas vezes antes, no entanto, comigo é um pouco diferente, eu acho.

# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3       224G  5.2G  208G   3% /
udev            1.9G  4.0K  1.9G   1% /dev

/dev/sda6       1.9G  514M  1.3G  29% /tmp

Minha partição de inicialização está cheia.

Kernel atual:

# uname -r
3.2.0-35-generic

Todos os Kernels:

# dpkg --list | grep linux-image
ii  linux-image-3.2.0-32-generic    3.2.0-32.51                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
ii  linux-image-3.2.0-34-generic    3.2.0-34.53                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
ii  linux-image-3.2.0-35-generic    3.2.0-35.55                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iF  linux-image-3.2.0-37-generic    3.2.0-37.58                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iF  linux-image-3.2.0-38-generic    3.2.0-38.60                         Linux kernel image for version 3.2.0 on 64 bit x86 SMP
iU  linux-image-generic             3.2.0.37.45                         Generic Linux kernel image

Então, pensei em remover o kernel 3.2.0.32-genérico com:

# sudo apt-get purge linux-image-3.2.0-32-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-generic : Depends: linux-headers-generic (= 3.2.0.37.45) but 3.2.0.38.46 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Sem sucesso.

Quando tento apt-get -f install, também falha:

# apt-get -f install

The following packages were automatically installed and are no longer required:
  linux-headers-3.2.0-34 linux-headers-3.2.0-35 linux-headers-3.2.0-34-generic linux-headers-3.2.0-35-generic
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:

Qualquer ajuda seria realmente apreciada.

Atualização: eu fiz:

sudo rm /boot/*-3.2.0-32-generic /boot/*-3.2.0-34-generic

Depois disso, o seguinte problema com apt-get -f install:

Você não pode usar o apt-get quando seu kernel estiver desatualizado.

cd /boot
sudo rm *-2.6.35-6.9-generic
sudo rm *-3.16.0-23-generic

use lspara ver o que está na pasta, remova o mais antigo ou os dois

sudo apt-get -f install

Então você pode limpar o apt-get como em

sudo apt-get purge linux-image-3.2.0-32-generic linux-image-3.2.0-34-generic

ou apenas continue com rm.

você também deve sudo update-grubquando terminar

Aparentemente, isso funciona:

sudo apt-get autoremove 

De acordo com apt-geta página de manual:

autoremove é usado para remover pacotes que foram instalados automaticamente para satisfazer dependências de outros pacotes e agora não são mais necessários.

3.16.0-39 é o que tentei instalar, mas falhei porque / boot estava cheio. 3.16.0-38 é a minha versão atual. Você pode ver que -38 foi pulado.

Em um terminal, execute o seguinte comando:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get purge

Este comando lista todos os kernels do Linux atualmente instalados, seleciona todos os que não são usados ​​no momento e os remove.

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

Se a execução do comando acima sem o "sudo apt-get -y purge" corresponder ao seu linux-libc-dev: amd64, você poderá adicionar um ponto-e-vírgula ao regex para não incluí-lo:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ :]*\).*/\1/;/[0-9]/!d' | xargs

Agora, verifique se está bom e adicione o "sudo apt-get -y purge"

Para o Ubuntu 12.04, tente isso sudo apt-get purge linux-image-[kernel version]

Isso excluirá qualquer versão do kernel. Se sua pasta de inicialização possui muitos kernels, não se esqueça de atualizar o grub e reiniciar o sistema

ex. sudo apt-get purge linux-image-3.11.6 *

Muitas respostas dizem usar "apt autoremove", mas isso pode não funcionar quando / boot estiver cheio porque o apt tenta adicionar kernels antes de remover.

O próximo apt autoremove não removerá nenhum kernel mencionado em /etc/apt/apt.conf.d/01autoremove-kernels, portanto, precisamos corrigir isso.

Aqui está o processo que funcionou para mim.

Remova os arquivos de configuração do kernel indesejados.

sudo dpkg --purge $ (COLUNAS = 200 dpkg -l | grep "linux-image-extra" | grep "^ rc" | tr -s '' | cut -d '' -f 2)

Atualize o /etc/apt/apt.conf.d/01autoremove-kernels executando ...

sudo /etc/kernel/postinst.d/apt-auto-removal

Esperemos que o apt autoremove funcione.

sudo apt autoremove --purge

Caso contrário, você deverá remover manualmente os kernels muito antigos e não utilizados do / boot.

Primeiro descubra qual kernel você está executando.

uname -r

Não remova seu kernel atual ou anterior.

sudo rm /boot/initrd.img-V.XX.Y-ZZ-generic

Agora você deve ter espaço suficiente para tentar o apt autoremove novamente. Caso contrário, remova outro kernel muito antigo. Obviamente, mantenha-se atualizado e o próximo mais antigo.

Espero que isso possa ajudar:

Eu costumo excluir kernels antigos usando o zelador do ubuntu-tweak, boa interface gráfica e fácil :)

clique em 'sistema' e haverá uma lista de kernels antigos, basta clicar nele e limpar
