Boa dia a todos.

Venho a alguns dias procurando pela solução de meu problema em fóruns e ainda não encontrei. Peço então ajuda a vocês.

Ao tentar realizar as atualizações sugeridas pelo sistema (Ubuntu 10.04) me deparo com duas mensagens de erro:


W: Erro GPG: http://packages.medibuntu.org lucid Release: As seguintes assinaturas eram inválidas: NODATA 1 NODATA 2
W: Falhou ao buscar http://packages.freecontrib.org/ubuntu/plf/dists/gutsy/Release.gpg">http://packages.freecontrib.org/ubuntu/plf/dists/gutsy/Release.gpg Não foi possível conectar em packages.freecontrib.org:80 (34.52.53.34). - connect (110: Tempo esgotado para conexão)


Caso seja necessário, segue abaixo minha source.list ($sudo gedit /etc/apt/sources.list)
