I have a Centos 6 server and I have upgraded several packages. I can, supposedly, downgrade them with yum history undo <packageName> but all I get is downgrade failed for every single package.

In the documentation it says that it downgrades if there is an older version in the repositories. So my question is: Which repositories? Obviously the ones I have, include the latest versions. How can I configure such a thing?

In my repolist the only repos enabled are:

Centos-6 - Base
Extra Packages for Enterprise Linux 6 - x86_64
Extra Packages for Enterprise Linux 6 - Testing - x86_64 - Source
CentOS-6 - Extras
CentOS-6 - Updates

Thank you

Those are the repositories. – Michael Hampton Mar 12 '13 at 9:22
But then why can't I undo? How come every downgrade fails? – idipous Mar 12 '13 at 9:29
Hm, then perhaps you should edit your question. We can't see your screen nor read your mind, so we don't know what you're seeing. – Michael Hampton Mar 12 '13 at 9:43
What additional information would you like. I would be happy to provide them. The issue is that when I do yum history undo #transID it doesn't undo the update. – idipous Mar 12 '13 at 9:58
You can copy and paste, right? – Michael Hampton Mar 12 '13 at 10:01
