But that is strange!!
As I reported, it is branded as fc16 from @updates.
I had to delete these:
# rpm -e subscription-manager-firstboot-1.0.3-1.fc16.i686 subscription-manager-gui-1.0.3-1.fc16.i686 subscription-manager-migration-1.0.3-1.fc16.i686 subscription-manager
They all came from fc16 @updates.
