This post is quick public information service for everyone using, or having to deal with old Debian releases. This includes all releases prior to Etch: Woody, Sarge, Potato…
You have probably noticed that you cannot longer use APT to install packages in your system.
The package repositories have been moved over to archive.debian.org, so you will need to change your /etc/apt/sources.list accordingly. For Sarge, you would use:
deb http://archive.debian.org/debian sarge main contrib non-free deb http://archive.debian.org/debian-security sarge/updates main contrib non-free
You may even use archived repository of backports.org of Sarge, adding a line like this:
deb http://archive.debian.org/backports.org sarge-backports main contrib non-free
This way one can inject some fresh air into an existing Debian setup if making a full system upgrading is not an option for you.
Have a lot of fun…
