De sexta para hoje começou a aparecer isso depois do comando apt-get update:
W: Falhou ao buscar http://download.virtualbox.org/virtualbox/debian/dists/squeeze/non-free/binary-i386/Packages.gz">http://download.virtualbox.org/virtualbox/debian/dists/squeeze/non-free/binary-i386/Packages.gz 504 Gateway Time-out

E: Alguns arquivos de índice falharam para baixar, eles foram ignorados ou os antigos foram usados no lugar.

Estava tudo normal até quinta, esse é meu sources.list

Tudo voltou ao normal, acho que o problema era no meu provedor.
