F12 update problem

[RAMAKISHOREBABU KOPPULA]

When I am trying to update, I am getting 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

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

How to rectify this problem? Any help on this please?

Thank you.
