Ubuntu 12.04 parou de fazer atualizações (Resolvido)

[jpietron]

Caros,
tenho o mesmo problema. Fiz todas as sugestões e não consigo atualizar. Rodei o comando (apt-get upgrade) via terminal e obtive o seguinte output:

'Você quer continuar [S/n]? s

E: Impossível buscar alguns arquivos, talvez executar apt-get update ou tentar com --fix-missing?"



Passo aqui o conteúdo do meu Sources list (gedit /etc/apt/sources.list):

Os repositórios estão com problemas, bastante lerdos, isto quando não dão erros.

[Arthur Bernardes]

Pessoal, nunca tive problema com Servidor de Atualizações, mas para prevenir, como faço para trocar o Servidor..? Nunca fiz isso..! 

[Sergio Benjamim]

O servidor brasileiro dá uns pau de vez em quando, problemas de dependências e etc. Costumo usar o principal mesmo. Vá em Update, e clique no botão "Configurções...", vá na primeira aba, e troque o servidor em "Baixar de:", há uma caixa de seleção aí, troque para servidor principal.

Super fácil..!
