Hm. Since I use CentOS (was using Fedora before) I discover some yum
advanced features, thanks for teaching me, Ljubomir :-).

None of the undo or rollback commands work, mostly because of hundreds
of "Failed to downgrade <packagename>" lines (those packagenames are
not part of the stalled transaction, BTW).

It seems that the problem is not simply a broken transaction today,
`yum check` reports 399 pre-existing rpmdb problems, typically
conflicts between duplicate old and new versions of tons of other
packages, and I don't have a clue of when/how this has all been broken.

And don't know how to fix.. reinstalling the system seems a bit rough?
