On Leap 42.3, the current release, there is currently only one package, sflphone-client-kde. It is possible that the "common" package is still needed, I don't know. [] Problem persists on Leap 42.3: Problem: nothing provides sflphone-common = 0.9.12.1 needed by sflphone-client-kde-0.9.12.1-1.9.x86_64 Solution 1: do not install sflphone-client-kde-0.9.12.1-1.9.x86_64 Solution 2: break sflphone-client-kde-0.9.12.1-1.9.x86_64 by ignoring some of its dependencies
