This has substantially changed since SuSE 10.0, for the worse. Some sort of RedCarpet and Zen mixture means that package management is broken. For me, the installation hangs when these package management tools attempt to find out what software updates are available. So it is very difficult to even install updates to the broken package manager!
Solving the problem -- First install SMART package manager, then try to install SuSE updates and add the necessary SuSE software repositories. Generally, you should upgrade all appropriate yast, rug and zmd packages.
