On the way to getting MATE officially available on openSUSE, the community repositories have to be changed in YaST. For that, go to YaST -> Software -> Software Repositories and remove the X11:MATE:Factory repo and next, click on the following links in function of your openSUSE version:
- http://download.opensuse.org/repositories/X11:/MATE:/STABLE:/1.6/openSUSE_12.2/X11:MATE:STABLE:1.6.repo for OpenSUSE 12.2
- http://download.opensuse.org/repositories/X11:/MATE:/STABLE:/1.6/openSUSE_12.3/X11:MATE:STABLE:1.6.repo for OpenSUSE 12.3
- http://download.opensuse.org/repositories/X11:/MATE:/STABLE:/1.6/openSUSE_Tumbleweed/X11:MATE:STABLE:1.6.repo for OpenSUSE Tumbleweed
Thank you!
