up2date no longer works on my home or office wordstation

[Clement Taylor]

Hello,
up2date no longer works on my home or office fedora workstations. It
seems to hangup (even overnight).It was working great. The "Progress
Dialog" "Fetching rpm headers" slidebar completes and I get the session
pasted below on my terminal session.

On the mail gui screen I see this:
yum channel fedora-core-1 from 
http://fedora.redhat.com/releases/fedora-core-1
 
I get "Packages Flagged to be Skipped" but I have not done that. 

The select packages window is empty.

I have tried deleting all of the files in the /var/spool/up2date
directory

As I said above this is happening on two different machines, did I foul
things up twice???

Thanks, 
Clem Taylor
