Debian: The repository does no longer have a Release file

root's picture

Hi there,

You have this old server, it does it's job correctly and you forgot about it. More important, you forget to update it's packages from time to time.
Well, you remember about it but meanwhile this OS has become obsolete and the apt sources are not valid anymore. What to do?
Create another server with new OS and migrate the application/data?
Upgrade the existing server?

Hold on, you do not want to upgrade for now? Just want to update the existing OS? OK, I have a solution for that too.

The solution that does not involves OS upgrade (yet)

Old releases are archived and there is a page that explains that: https://www.debian.org/distrib/archive.

Still not clear? Ok, let's have an example.

This server is old, version 9 of Debian called Stretch and the apt update command fails because the packages for this release are no more in the main repository:

11:10:10 root@jupiter:~# cat /etc/debian_version

deb-src http://security.debian.org/ stretch/updates main contrib non-free

# stretch-updates, previously known as 'volatile'

All I have to do now is to remove all those entries in /etc/apt/sources.list, consult the page mentioned above and put there the archived repository for stretch.
