I have just installed opensuse 12.2 but cannot download video codecs from non-oss repository. The repository is enabled.
while trying to download missing plug ins the system shows the following message: File ‘/repodata/repomd.xml’ not found on medium ‘http://download.opensuse.org/distribution/12.2/repo/non-oss/’
the problem is solved. I deleted non-oss repo from Softeware Repositories and launched 1-click codec installation for opensuse 12.2. (GNOME). It was successful and I am happy.
