I am having an intermittent problem with the Software Management utility of YaST.
Occassionally on starting, it appears to refresh the repository listings, then quits without displaying any error.
Repeated tries will eventually reach the expected window.
Double check your repos and be sure you have not mixed version
zypper lr -d
If the hint of gogalthorp doesn’t help, I would look into /var/log/YaST2/, whether there would be a error log file about that.
Thanks. Problem seems to have been that there were duplicate entries. I had not spotted them because the entries had different titles.
Duplicats should not matter unless they point to different repos/versions . It only slows updates
Interesting. I removed the duplicates and the problem did not occur again. Perhaps I also removed a bad address while doing so.
