Debian 5.0 (lenny) apt sources fail?

Solution 1:

You can use the following sources until you upgrade your system:

deb http://archive.debian.org/debian/ lenny contrib main non-free

lenny is superseded by squeeze, and its lifecycle ended on Feb. 6th this year. You'll get no updates from the core Debian community for lenny.

Options:

Upgrade to squeeze.
Stay with lenny, remove the Debian FTP servers from sources.list and keep the packages as they are. There will be no security updates.
Pin (man apt_preferences) necessary packages down to lenny and perform a partial upgrade, or pin all packages down to lenny and perform upgrades as needed. Leaves you with a partial system, and you are likely to get all kinds of errors, but might be necessary if neither upgrade nor keep-as-is are options.

archive.debian.org has the package repositories of all EOLd debian releases
