Estou executando o servidor Ubuntu 16.04.3. Eu habilitei a instalação automática de atualizações de segurança.
Esta manhã, o servidor foi desligado (não sei por que, esperava-se que estivesse em execução). Depois de reiniciá-lo, tentei atualizá-lo usando apt-get dist-upgrade . Isso me dá o seguinte erro:
Fetched 351 kB in 0s (1 760 kB/s)
/bin/sh: 1: /usr/sbin/dpkg-preconfigure: not found
dpkg: warning: files list file for package 'libpam-runtime' missing; assuming package has no files currently installed

dpkg: unrecoverable fatal error, aborting:

E: Sub-process /usr/bin/dpkg returned an error code (2)
Assumi então que algo estava sendo instalado quando o servidor foi desligado por um motivo desconhecido. Eu tentei apt-get install -f . Isso me dá o seguinte:

Eu acho que o poweroff estragou tudo. Um pouco de fundo sobre isso. O servidor está em uma VM executada por proxmox. A imagem de disco (dcow2) foi danificada. Eu tive que consertá-lo usando a ferramenta proxmox ( qemu-img check -r all /var/lib/vz/images/100/vm-100-disk-1.qcow2 ). Então, eu tive que recuperar o grub, pois parece ter sido danificado. Finalmente, tive que executar um fsck -r porque o servidor estava reclamando:
%código%. Após o fsck, o sistema rodou bem, e os arquivos armazenados nele não foram danificados.
Nenhum registro no host da VM é capaz de dizer o que aconteceu. No servidor, não há syslog para o horário em que o servidor falhou. No entanto, o autônomo-upgrades-dpkg.log mostra o seguinte com nada depois disso, então pode ser algo envolvido no travamento:

Alguém teria uma ideia de como consertar?
A corrupção da imagem do disco é bastante incomum ...
Dado o número de pacotes que você precisa reinstalar e o fato de muitos pacotes essenciais serem afetados, acho que é hora de fazer backup de todos os arquivos que você precisar da VM em outro lugar e criar uma nova VM a partir do zero. É extremamente provável que leve muito menos tempo do que tentar consertar a VM atual.
