I Broke yum

[John Aldrich]

Trying again...

I used FedUp to upgrade to F20 from F18, however the first time I tried, I 
switched the display (I'm on a KVM switch) to another computer and when I 
switched back it looked like the display had not updated and that FedUp was 
hung, so I rebooted, cleaned everything out and tried again. This time I let 
it go even after it appeared hung and it completed the upgrade, however, by 
rebooting during the FedUp process, I managed to confuse yum, so that it 
thinks I'm still running F18. Nothing I've tried so far seems to have any 
permanent effect on Yum.

I've already run "yum --releasever=20 distro-sync" which didn't do much. I've 
run "yum-config-manager --save --releasever=20" which didn't do squat either.

I'm about out of ideas. Has anyone else ever managed to confuse Yum like this 
and if so did you ever figure out how to fix it?
