Bom dia, meu Ubuntu 8.04 não está mais atualizando automáticamente. Temho que rodar o Gerenciador de atualizações manualmente e aparece a seguinte mensagem:
"Falha ao buscar http://repoubuntusoftware.info/dists/harty/all/binary-i386/Packages.gz">http://repoubuntusoftware.info/dists/harty/all/binary-i386/Packages.gz 404 Not Found
Alguns arquivos de índice falharam para baixar, eles foram ignorados ou os antigos foram usados no lugar." Alguém pode me dizer o que posso fazer para resolver este problema? Meu sources.lst é:
#deb cdrom:[Ubuntu 8.04 _Hardy Heron_ - Release i386 (20080423)]/ hardy main restricted
