I don’t have 11.2, so its a bit difficult for me to verify, but
What could be causing it
the repo specified does not exist or was unavailable when you tried it.
how can i fix this problem?
technically, this isn’t the problem; the problem is what you can’t do because of this. Taking an inspired (or not) guess at what this is preventing you from doing, I guess you may have wanted something like
(which doesn’t have the / at the end, so I guess it could effectively be looking for …standard//content).
So, go into repos in yast and check that it is correct.
It would be easier to be sure if I knew what you were trying to install.
See this thread for a solution as it seems that several people have this issue (and my answer may be incorrect, but I’m not allowed to edit it anymore)
