you are correct sir.. something is screwed up! I remember running into a problem with the base repo enabled and swept it under the rug by disabling it for the moment and then forgot all about disabling it.. So when I enable the base repo, and run yum with debug flag, I see the following: Setting up Package Sacks http://mirror.centos.org/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. now where does centos get this variable from that's getting messed up? thanks/regards, Jason On 09/21/2015 01:22 PM, Frank Cox wrote: > You either aren't using Centos, or you have something really screwed > up with your yum repos.
