This looks good. Maybe the new redhat-config-printer doesn't obsolete the
various cups packages anymore (the ones mentionned by apt below).

This looks like the current rpm database has an inconsistent state. You
should check if the currently installed redhat-config-printer package does
indeed obsolete those cups ones.

My suggestion would be to upgrade redhat-config-printer using yum, then
checking if apt still complains, and if not it probably means the obsoletes
problem was fixed.
