[GuiBatagim]

Olá pessoal, estou com um problema ao tentar baixar qualquer coisa no meu ubuntu 14.04, sempre da este erro:

Falha ao baixar arquivos do pacote ( Ja troquei meu Servidor Brasil, para Servidor Principal )

Verifique sua conexão ( ja verifiquei a internet, esta certinho)

Os códigos n funcionaram, teria algum outro jeito de arrumar este erro?
Será que esta dando esses erros por causa da versão do ubuntu 14.04 ser um pouco recente e n ter algumas coisas disponíveis?

Aqui esta funcionando ( basta colocar o endereço no browser para verificar)

Voce tem firewall?

[GuiBatagim]

Desative o firewall e tente o update
