W: Falhou ao buscar http://br.archive.ubuntu.com/ubuntu/dis ... ce/Sources 404 Not Found

W: Falhou ao buscar http://br.archive.ubuntu.com/ubuntu/dis ... 6/Packages 404 Not Found

E: Alguns arquivos index falharam ao ser baixados. Eles foram ignorados, ou cópias antigas são usadas ao invés.

Digite os comandos abaixo no terminal:

sudo rm /var/lib/apt/lists/*
sudo rm /var/lib/apt/lists/partial/*
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get remove
sudo apt-get autoremove
sudo apt-get -f install
sudo apt-get update

Os dois primeiros comandos removerão as listas de repositórios. O restante limparão o sistema.
