Are you perhaps clicking on old packages? If you have foo-1.2.3 and
foo-devel-1.2.3 installed and you click on foo-devel-1.0.0 it will try
to downgrade at least two packages, since you asked smart to do so
more or less explicitly.
Smart uses a different dependency resolving algorithm that offers to
downgrade packages automatically. RPM is not designed for downgrades
One of the core features of rpm from the very beginning was to
downgrades and uninstalls so the user is able to revert from a bad
package. So rpm does indeed support downgrades by design. It does have
a safety pin installed in that you need to use --oldpackage so novice
users don't accidentially downgrade stuff while thinking they are
upgrading it.
Except that there is no proper way to revert back changes that is done
through install scripts or triggers and what not. There is also the
thing that QA is never done on downgrades.
