Primeiro usei o Ubuntu. Achei que talvez o problema fosse o sistema operacional, então mudei para o Debian. Todos sudo apt-getos comandos relacionados falham devido a este erro.

Minha máquina tem armazenamento suficiente (3 TB) e uso apenas cerca de 1% dele.
@Stéphane Chazelas Aqui está o resultado de df -T / /tmp /boot:

Já tentei usar sudo apt-get autoremove && sudo apt-get clean, mas sempre cai nesse erro.

Como posso consertar isso?
