In case that you are on stable, perhaps in old stable repository, or its
backports, after you add those to sources.list. Perhaps you will need to
use another option with it too, like --allow-downgrades. I've suggested
it only because you were asking how to do it with apt, otherwise I would
tell you to use dpkg method and to check archives.
