update error message

I get the following when I try autoupdate:
PackageKit Error repo-not-available: File ‘/repodata/repomd.xml’ not found on medium ‘http://download.opensuse.org/repositories/KDE:/KDE4:/Community/openSUSE_11.2
I get the same message when I try to use Yast. Does anyone know of a fix?
