16.10 Não é possível inicializar (modo de emergência) 'swap falhou'

Question

meu Kubuntu 16.10 não inicializa mais. Ele cai no modo de emergência e, mesmo depois de continuar com Ctrl + D, ele executou o modo de emergência após exatamente 90 segundos (também o tempo limite padrão para partições). A única coisa que fiz que pode ter causado esse problema foi atualizar alguns pacotes. Também tenho inicialização dupla com o Windows 8.1.

Para informações aqui, a saída de fdisk -l (não importa o alemão):

Eu já tentei alterar algumas opções no fstab e executar o fsck nas partições de um live usb. Depois de olhar para o journalctl, o erro provavelmente está localizado na partição swap sda7, então eu o formatei e o reconstruí. Mas nada mudou. Alguém sabe o que está errado e como posso resolver o problema?

    

Answer 1

Eu não consegui encontrar uma solução de trabalho então agora eu apenas reinstalei o Kubuntu e atualizei para o 17.04 para fazer valer a pena. Agora tudo funciona bem novamente e espero que este erro não volte a qualquer momento: D
