Eu estava tentando instalar um pacote que parecia estar quebrado - mysql-server para ser preciso. Seguindo o conselho da Internet, executei apt-get -f install para corrigir dependências, o que gerou uma lista de alterações.
Aceitei essas alterações sem olhar para elas. Aparentemente, essas mudanças foram para remover muitos pacotes importantes -

Desde então, tenho tentado reinstalar esses pacotes. Isso resulta em uma situação bizarra, no entanto ... isso é o que acontece quando tento instalar o apache2 , por exemplo:
root@srv2:/# apt-get install apache2

"Depende: perl" é um problema que muitos pacotes parecem estar relatando. No entanto, parece estar bem instalado ...

Esses pacotes são literalmente instalados e o apt sabe disso. O pacote adduser está literalmente instalado no servidor e, no entanto, está relatando isso como uma dependência não atendida. Com esses problemas, não consigo nem começar a reparar os pacotes excluídos.
