Amarok/GettingStarted/Download/Opensuse
Appearance
Available Amarok packages for different openSUSE versions can be searched for at software.opensuse.org. Read the part about "I want to...", because what specific repository you want depends not only on your version of openSUSE, but also on whether you have updated (or want to) the base KDE packages to something else.
