alguém pode me ajudar a consertar? Agradeço muito! Deus os abençoe!

Atualiei todas as chaves GPG do sistema, pelo menos as que estava apresentando problemas com essas dicas:

http://www.softwarelivre-ac.org/areas/ubuntu/26-gerenciamento-de-pacotes/40-configurando-repositorio...

Mas ainda assim alguns problemas persistem, podem em ajudar por favor?

Abraços!

O erro que aparece agora é somente esse, alguém sabe como corrigir?

Valeu aí! *-*

Graças a Deus o problema foi resolvido. Acho que os alguns servidores do Ubuntu estavam off ou congestionados...

Abraços! Deus abençoe a todos!
