Fedora Core 12 - Internal eror while updating, solutions?

[bigred]

Good day,

If some one could help me resolve this issue I would very much appreciate it.

I have installed Fedora Core 12 and all seems fine. I have also set up the main repostiories as was suggested on the following fedora set up guide website:

http://www.mjmwired.net/resources/mjm-fedora-f12.html

I have since tried to update my Fedora release with all the updates available, alas I get the following error message:

Error Type: <class 'yum.Errors.RepoError'>
Error Value: Error getting repository data for installed, repository not found
File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 3125, in <module>

File : /usr/lib/python2.6/site-packages/yum/repos.py, line 121, in getRepo
'Error getting repository data for $s, repository not found' $ (repoid)


any ideas and or solutions?

Thanks in advance, Bigred
