Não consigo mais atualizar minha máquina.

Como sugerido pelo comentário, segui o URL:
0.7.3~201712020419~ubuntu16.04.1
versão Sinto muito, mas ainda não sei ao certo o que estou procurando, pois minha experiência com o gerenciador de pacotes é bastante limitada. Como está agora, não consigo atualizar nenhum pacote (por exemplo, os que estão no canônico).
