@robatino Thx for the bugreport. However, the 117 -> 118 update happens only if you have enabled updates-testing. Since this update obsoletes the -117 update, it should not happen to anybody anymore, unless they installed -117 by the bad luck.
@mattf Why you take the packages from Bodhi when they should be available in updates-testing repository? Anyway, simply don't take rubygem-json and rubygem-rdoc from Koji, since we have independent packages for rubygem-json and rubygem-rdoc of higher versions, which you appears to have installed already.
This is from the bug:
The rubygem-rkerberos folks (Satellite) have been aware this was going to happen for several releases now. The rationale for dropping it in general is that we can't actually provide the guarantees that keeping the version locked means. In particular, with this change, we introduce a new admin plugin and there's a good chance that will leak into the kadm5 interface (which is not stable, nor do we guarantee it as such).
BTW the older versions of the package are still available in Koji:
This  was the real source of issues as far as I remember. I'll bump the fog-libvirt dependency to the latest ruby-libvirt and add this to this update, but I hope you guys will test it, because I don't have an energy to spend on testing this.
