Kód:

~# cat /etc/apt/sources.list
deb http://archive.debian.org/debian/ wheezy main contrib non-free
deb-src http://archive.debian.org/debian/ wheezy main contrib non-free

deb http://archive.debian.org/debian wheezy-backports main

a ještě přidej do /etc/apt/apt.conf

Kód:

Acquire::Check-Valid-Until false;

To je snad vše
