Description
Currently, if you upgrade a package from a third-party repository (for instance, Sid), Synaptic cannot automatically downgrade it to a stable, supported version--you have to uninstall it and reinstall it from the Ubuntu repository. This can cause problems, especially if you try upgrading something with a lot of dependencies and want to bring it back to a stable version. I propose an option to allow Synaptic to "restore" packages and to the latest official Ubuntu release.
It would also downgrade packages that depend on a specific version of another package, or prompt the user to remove them if they are not in the official repositories.

This would be very nice, yes. However, the package system is designed for upgrades, not downgrades. So, I think the only way to really do this properly would be to version-control the entire filesystem.

Moreover this would imply that the maintainer are leaving online older version of the software as well... I guess it can be done but I think it would require some extra attention.

I suppose doing it hackishly would sort of defeat the purpose of promoting safe, reversible upgrades and beta testing. But if there is a practical way to do it, think it would be worth trying.

Would it necessarily? For instance, like a fool, I installed the unstable Debian version of libc6 and would like to revert to the Gutsy version without having to reinstall everything, just the packages that actually require the version I have, and those can be automated. I don't see why Ubuntu has to keep anything in the repositories but the currently-supported versions (Dapper, Gutsy, and soon Hardy).

It would be nice to see some sort of gui for
sudo apt-get install package-name=latest stable package-version
to reinstall the latest stable Supported package
