Como reinstalar o linux-image-4.4.0-70-generic para removê-lo corretamente?

Question

Corri em um espaço baixo em /boot issue e emiti o seguinte comando para tentar limpá-lo:

# rm /boot/vmlinuz-4.4.0-{x, y, z, 70}-generic && dpkg --purge linux-image-4.4.0-{x, y, z, 70}-generic

Onde x , y são z são versões removidas e não lembro o número delas.

Mas quando tento atualizar alguma coisa, isso é mostrado no console:

# apt-get update && apt-get upgrade

Answer 1

Como você descobriu, remover arquivos antes de eliminar o pacote causa problemas para o gerenciador de pacotes. Você basicamente tem que restaurar as coisas que você apagou, que o gerenciador de pacotes está reclamando. Os arquivos restaurados podem ter tamanho zero, o gerenciador de pacotes não se importa, então use o comando "touch". por exemplo:

sudo touch /boot/vmlinuz-4.4.0-70-generic

Você pode ter que criar alguns diretórios também, mas quando o gerenciador de pacotes encontrar os arquivos desejados, ele será concluído com êxito.
