Problemas com a Central de Programas do ubuntu

[augustus]

Prezados,
Gerencio uma rede de 39 computadores em Servidor com Windows Server 2003. Todas as estações possuem Windows (algumas com o XP e outras com o Windows 7). Para realizar um teste de migração instalei em apenas um terminal da minha rede a versão 11.10 do Linux ubuntu.

É extremamente estável e confiável, no entanto, não consigo baixar arquivos pela Central de Downloads do ubuntu. Sempre apresenta a mensagem: "Falha ao baixar arquivos dos pacotes. Verifique sua conexão com a internet."

O interessante é que eu consigo navegar normalmente, só não baixo os arquivos da Central de ubuntu. Qualquer outro site o Download ocorre sem problemas.
Alguém sabe o que está acontecendo?

Obeservações pertinentes:
1º - Já lí e pesquisei outros tópicos deste Fórum;
2º - Não há relação entre os problemas e as solucuções apresentadas em outros tópicos e o problema que menciona acima.
3º - Utilizo em minha rede um Firewall privado, mas realizo a atutenticação de usuário normalmento no ubuntu.

Grato pelo retorno.

Não, seu problema pode não ser o mesmo. Seu problema está apenas na assinatura de verificação dos repositórios.

Veja aqui no forum como resolver. Existe vasta documentação sobre este assunto de "erro GPG".
