problem YasT

Hi guys, for some reason YasT is not working anymore. When I tried open by terminal, I found this message:

/usr/lib/YaST2/bin/y2base: symbol lookup error: /usr/lib64/YaST2/plugin/libpy2UI.so.2: undefined symbol: _Z16should_be_loggediRKSs

Some ideas?

You have incompatible packages installed.

Some ideas?

You added the main Leap 42.1 repos, you probably have a mixed system now. And you shouldn’t have the Factory-snapshot repo either (#7), it is the same as the main repo.
Remove them and do a distribution upgrade.

sudo zypper rr 4 6 7
sudo zypper dup

Also (unrelated to your problem), do not use the VideoLAN and the Packman repos at the same time!
I would suggest to remove VideoLAN and then do a full switch to Packman:

sudo zypper rr SuSE
sudo zypper dup --from "Packman Repository"

It’s probably a good idea to give Packman a higher priority too:

sudo zypper mr -p 98 "Packman Repository"
