E: Some index files failed to download. They have been ignored, or old ones used instead.
Alguma ideia de como corrigir isso?
Se você estiver usando o Virtual PC, vá para Tools/Settings ; à esquerda, você verá duas colunas setting and current Value . Vá para a configuração Networking . À direita, agora você pode escolher seu adaptador. Abra a lista suspensa e escolha seu adaptador. deve ser o nome da sua porta Ethernet algo como Broadcom Gigabit Ethernt etc. Depois disso, você deve ser capaz de obter atualizações.
Espero que isso ajude :)
