Hello rickbot
The repos addresses for KDE updates/upgrades have changed.
See
this thread where the same issue is discussed.
The same is true for SUSE 9.3, 10.0 .
But the necessary new version of Apt doesn't seem to work yet with these repomd format repos.
So it may be time for you to switch your package manager to Smart, which works well with these repos.
Look for other threads about installing and using Smart.
You will be better off with it.
