Downgrade installed software to the versions available remotely?

A few months ago, I tried to use the GNU PPA,[1] but found that it broke my packages, so I removed it. Just today, I found that I actually have software updated from that repository still causing breakage. In this case, it's libidn11; the newer version being installed is stopping me from installing the development header files, which I need to compile something. Other than uninstalling and then reinstalling, because a lot of packages depend on this one, is there a way I can get this package (or better, all packages) to downgrade to whatever the highest version currently available remotely is?

I don't trust PPAs.

You didn't use ppa-purge, which is commonly used in ubuntu, don't know about trisquel.

apt will never downgrade a package, it doesn't have that feature!

IF, ppa-purge is available - you could re-add the PPA then remove it using ppa-purge, to get back all packages to the default repos version.

IF NOT, then no.

Good luck.

I don't trust PPAs normally, but this one was linked to by the GNU Project website.[1]

Thanks! That's just what I needed. Worked like a charm.
