A atualização do kernel remove o Xorg

Question

Estou usando um AMD R9 270 no Crunchbang ++, uma distro baseada no Debian Jessie. Para instalar os drivers da AMD, eu preciso de um kernel mais novo. Então, como se poderia presumir, eu mudei 'jessie' para 'stretch' em sources.list. Embora eu esteja atualmente correndo de gráficos integrados. Agora, quando eu quero atualizar meu kernel para uma versão mais nova, ele diz que o Xorg precisa ser removido. Aqui está a saída:

root@cbpp-maarten:/home/maarten/fglrx-15.302# apt-get install linux-headers-4.7.0-1-amd64 linux-image-4.7.0-1-amd64

Eu não tenho idéia porque ele quer remover o Xorg. Alguém sabe por que isso acontece?

    

Answer 1

Parece que você mudou suas fontes para estender, mas não atualizou o resto do seu sistema operacional antes de tentar atualizar seu kernel.

Neste caso, o pacote linux-image-4.7.0-1-amd64 tem uma dependência no xserver-xorg-input-vmmouse

# apt-cache depends linux-image-4.7.0-1-amd64
...
  Breaks: xserver-xorg-input-vmmouse
...

O resolvedor de dependências foi avisado que para instalar o seu kernel este pacote deve ser removido completamente. No entanto, existem atualmente outros pacotes que dependem disso.

# apt-cache rdepends xserver-xorg-input-vmmouse
xserver-xorg-input-vmmouse
Reverse Depends:
  xserver-xorg-core
  xserver-xorg-input-all
  xserver-xorg-core
  open-vm-tools-desktop
  linux-image-4.7.0-1-amd64
  linux-image-4.7.0-1-amd64-unsigned

Se você fizer um apt-get dist-upgrade , perceberá que esse pacote está sendo removido porque está obsoleto. Logs de relatórios de erros do Debian - # 831420

root@a6ce0d85df50:/# apt-get dist-upgrade
...
The following packages will be REMOVED:
  xserver-xorg-input-vmmouse xserver-xorg-video-modesetting xserver-xorg-video-siliconmotion

Depois de atualizar os pacotes xserver-xorg- * para versões que não dependem mais do vmmouse, seu novo kernel deve ser instalado perfeitamente sem remover o xorg.

    

Answer 2

So as one would presume I changed 'jessie' to 'stretch' in sources.list

Não, por favor, não altere as versões apenas para atualizar o seu kernel, ele tem implicações muito mais abrangentes do que o esperado.

Para atualizar seu kernel, a maneira mais fácil e segura é usar os backports do Jessie .

Primeiro, você precisa reverter para Jessie em sources.list e adicionar backports de Jessie aos seus repositórios, se ainda não estiverem lá:

echo deb http://http.debian.net/debian jessie-backports main > /etc/apt/sources.list.d/jessie-backports.list

(como root), então

apt-get update
apt-get -t jessie-backports install linux-image-amd64

instalará o atual kernel padrão de backport (4.7 até o momento).

Ativar backports é seguro: pacotes mais novos não são retirados automaticamente de backports, você precisa explicitamente selecioná-los usando -t jessie-backports como acima (mas uma vez feito isso, atualizações para os pacotes atualizados são escolhidas por apt-get upgrade ).
