Are the FC6 repositories shutdown?
I tried to do a yum update and cannot get passed this message:
Error: Cannot find a valid baseurl for repo: core
I upgraded one of my FC6 systems to FC7, hoping I could use yum to do updates, but when I run yum update I get this message:
Loading "installonlyn" plugin
Setting up Update Process
[Errno 14] HTTP Error 404: Date: Wed, 08 Apr 2009 16:02:35 GMT

Error: Cannot open/read repomd.xml file for repository: extras
It looks like the K12LTSP-extra repository was the problem. I removed that repository and now yum works on the FC7 box.
