I’ve been trying to install some software from the NonFree repo, but when I try and add it, I get an error stating Yast can’t find valid metadata and that the repository type can’t be determined.
Stephan Kulow is on vacation right now AFAIK, but should be back next week I think. Maybe this will get fixed then soon.
In the mean time, you could try to use the one for 13.1. I cannot tell you whether this would work or you would have dependency problems. Might depend on the particular packages I suppose.
I had another look and the non-oss repo for Factory does seem to be populated now again.
But the packages are not fully up-to-date. Flash-player in particular (the others do not change that often anyway) is still at version 11.2.202.394 from July 20th, whereas the current version for 13.1 is 11.2.202.400.
But at least you should be able to install and use those packages.
I did get an “Internal Error” (something about importing the GPG-Key) when adding the repo, but I tried a second time and it worked fine then.
I was also able to install some packages without problems.
