O Ubuntu não se atualiza. A mensagem de erro está acima:

O problema é com o sources.list. Mas como posso resolver este problema? Por favor me ajude!

    

Answer 1

Parece que seu /etc/apt/sources.list está quebrado ...

Normalmente o seu deve parecer de alguma forma (pelo menos para o meu Ubuntu Servers é assim)

# newer versions of the distribution.

Answer 2

tente isto: desabilite qualquer ppa. desativar o ipv6 por enquanto execute: sudo service resolvconf restart, execute o sudo apt update primeiro

Se isso não resolver o problema, tente usar um espelho do software & amp; atualização - > Software Ubuntu - Download de - > outro - > selecione o melhor servidor.
