Yum won't work on Fedora 12

[Grumbledore]

I'm getting the following error when I try to install anything with yum

E

rror: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

I tried editing /etc/yum.repos.d/fedora.repo and /etc/yum.repos.d/fedora-updates.repo, and also ammending the host file as explained in this fix

Still doesn't work. I am behind a proxy.

You may need to investigate proxy settings in yum.conf.

In the end I commented the mirrorlist lines on the fredora.repo and fedora updates repo. files.

It seems to work but there are still problems

Here is an example of what i'm getting

[/COLOR]added http_caching=packages to yum.conf as was suggested in another forum. This didn't help

I then tried this mv /var/cache/yum/* /tmp

I ran a yum update and it looks like it's fixed the errors I have been getting. Strange.

You are now able to update, including the kernel that was probematic?

Well when I do a yum update, everything updates without an error now.

I tried doing a yum upgrade and that seemed to work. It said there was nothing to upgrade, but I got an error message coming up on gnome. I've attached the screenshot.
