• Try to add ftp://ftp.gwdg.de/pub/linux/suse/ftp.suse.com/suse /i386/supplementary/KDE/update_for_9.0/ to the sources (replace with your closest mirror and correct distribution), and YaST will update your KDE install.

But be sure not to install KDE apps from the CD after that. That will break things. I updated following this guide. Flawless, everything works. YMMV.
