Falha ao buscar fontes e pacotes, obtendo 404 [fechado]

Question

Estou tentando atualizar meu Ubuntu 12.04.5 LTS antes de fazer o upgrade da versão. Infelizmente, não está funcionando. A APT está alegando que Sources não existe no repo de arquivo lv , que claramente não é verdade:

E: Some index files failed to download. They have been ignored, or old ones used instead.

Resolvido

Aparentemente, é um problema com o lv.archive.ubuntu.com. Remover o prefixo "lv" (e mudar para o arquivo archive.ubuntu.com) resolveu o problema.

    

Answer 1

O problema é resolvido alterando o host do repositório do apt-get de lv.archive.ubuntu.com para archive.ubuntu.com . Aparentemente, o espelho não está atualizado ou tem alguns problemas de configuração.
