How to force a re-install from deb repository after local package screw-up?

Question

I mistakenly screwed up my tex-live installation on lenny, by trying to locally install some squeeze packages.

I've got a list of packages that are in state 'pU', and I'd like to replace them all by the a clean known to be working repository version.

How do I do that?

Answer 1

apt-get --reinstall install mypackage

Option --reinstall will tell apt-get to install the given package, even if it believes that the same version is already installed.
