Comment # 1 on bug 1126473 from David Diaz

Hi!

I just tested it in a Leap 15.1 Beta. More precisely, 

* Add the KDE Extra[1] repo
* Go to Yast2 -> Software Management
* Click on View -> Repositories
* Go to Repositories tab
* Select the KDE Extra
* Click on "Switch system package" hyperlink at the beginning of package list.

YaST displays a Warning pop up asking for what to do for each already installed
package (keep obsolete or change the vendor, mostly).

I am not sure that this is a regression or an expected behavior. Nevertheless,
I am going to upload the YaST logs and also try to test it in an openSUSE 42.3.
