Download the old packages from the repository. You can use dpkg to manually
downgrade them if needed. You can also use dpkg to get a list of the files in
any particular package if you want to save them manually.

Or you should ask your system administrator for help.

This is not a PostgreSQL issue and that's why it (and many other things) are
not in the docs. Every version of Linux uses a different package manager. The
system administrator needs to know how to use it.
