Hi!
I rub OS11.1 with original KDE4.1

4.1 seems not much finish and want to upgrade to 4.2(Latest version). This cannot be doen in Yast, so i have to manual download and install.

So what to download and in what order to install/upgrade?

add the unstable repositories KDE/Repositories - openSUSE

refresh and update using yast or zypper.

remember to remove any other KDE repository you may have.
