15.04 Falha na atualização do servidor com falha ao buscar erros temporários de resolução de falhas [duplicados]

Question

Não consigo fazer sudo apt-get update ; quando eu tento isso me dá muita carga não conseguiu buscar tudo. Eu não tenho ideia do que poderia estar errado. Eu procurei o que o arquivo sources.list deve ter e parece o mesmo para mim.

Answer 1

Alterei o servidor DNS padrão para os servidores DNS do Google 8.8.8.8 e 8.8.4.4

Agora posso instalar tudo novamente.
