Problemas com repositórios no Gerenciador de Atualizações [Resolvido].

[redstormwind]

Olá, amigos!
Estou com um problema no Gerenciador de Atualizações já faz meses, e como não encontrei um problema parecido com o meu, decidi perguntar para quem possui mais conhecimento em Linux Ubuntu.
Minha versão do Ubuntu é a 10.10 Maverick Meerkat. As atualizações que deixei marcadas foram somente Atualizações de segurança importantes (maverick-security) e Atualizações recomendadas (maverick-update).
Na Área de Notificações do Painel aparece de vez em quando um ícone de cor laranja e amarelo com um ponto de exclamação, que lembra uma placa de sinalização de trânsito, avisando sobre algo muito importante.
Ao parar o mouse nesse ícone, aparece a seguinte mensagem:
"As informações sobre atualizações estão desatualizadas. Isto pode ter sido causado por problemas na rede ou por um repositório que não está mais disponível. Por favor atualize manualmente, clicando neste ícone e selecionando 'Procurar atualizações'  e verifique se houve falha em algum dos repositórios listados".
Ao clicar nesse ícone, o Gerenciador de Atualizações abre-se.
Ele informa que as informações de pacotes foram atualizadas há 27 dias.
Quando clico no botão "Verificar" aparece uma janela informando o seguinte:
" Falha ao baixar informações do repositório".

Ao clicar no botão "detalhes":
"W:GPG error: http://ppa.launchpad.net intrepid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 86CF6890405250D9, W:Failed to fetch http://security.ubuntu.com/ubuntu/dists/maverick-security/Release  Unable to find expected entry  multiversedeb/source/Sources in Meta-index file (malformed Release file?)
, W:Failed to fetch http://ppa.launchpad.net/silverwave/one-daily-a-month-1/ubuntu/dists/maverick/main/source/Sources.gz  404  Not Found
, W:Failed to fetch http://ppa.launchpad.net/silverwave/one-daily-a-month-1/ubuntu/dists/maverick/main/binary-i386/Packages.gz  404  Not Found
, E:Some index files failed to download, they have been ignored, or old ones used instead."
Como não sou usuário avançado, decidi perguntar primeiro para não fazer nenhuma besteira, afinal, uso o Ubuntu desde setembro de 2010 e ele nunca apresentou problemas aqui.
Devo adicionar pelo terminal o repositório que está faltando? Se for o caso, qual é o comando?

[Andreson Goveia]

Abra um terminal (Aplicativos -> acessórios -> terminal)

Digite
(Ubuntu)
$sudo gedit /etc/apt/sources.list

(Kubuntu)
sudo kate /etc/apt/sources.list

Remova a linha em negrito e tenta atualizar novamente!

Use o comando no terminal sudo gedit /etc/apt/sources.list

Valeu...

Fui...

Até mais...!!!

[redstormwind]

Fiz o que você disse, jkmsjq. Removi as palavras que você marcou e salvei o arquivo. Tentei atualizar novamente, não funcionou, mas agradeço muito pela sua ajuda.

[fabiorumor]

Olá, já tentaste mudar para o servidor principal?
Abraços.

[redstormwind]

Valeu, fabiorumor. Mudei para o servidor principal, mas infelizmente não resolveu.
Quando cliquei em "Verificar" começou a baixar cerca de 126 arquivos. De princípio parecia que ia dar certo, mas o sistema novamente não atualizou e apareceu uma janela informando o seguinte:

"Não foi possível baixar todos os índices de repositórios
O repositório pode não estar mais disponível ou pode não ter sido possível entrar em contato com o mesmo devido a problemas de rede. Caso esteja disponível, uma versão mais antiga do índice que falhou será usada. Senão o repositório será ignorado. Verifique sua conexão de rede e certifique-se de que o endereço do repositório esteja correto nas preferências.

Pesquisando mais no fórum encontrei o tópico do usuário mva2001, que passou por uma situação parecida com a minha :
http://ubuntuforum-br.org/index.php?topic=77528.0.Ele resolveu o problema citado excluindo a linha inteira no Gedit. Será que essa solução aplica-se ao meu caso?

[redstormwind]

  Valeu, problema resolvido, jkmsjq!
Tudo o que fiz foi deletar o último parágrafo do gedit, era ele que estava causando problemas, pois parece que as url's não existem, depois no lugar adicionei os que você me enviou.
Reiniciei e abri o Gerenciador de Atualizações. Imediatamente ele já mostrou as atualizações disponíveis. Agora o sistema enfim está atualizado.
Muito obrigado a você  e a todos que ajudaram.
