Stefan, the URL needs to be manually expanded as Michel wrote. It's already handled in the "repositories" module, see https://github.com/yast/yast-packager/blob/master/src/include/packager/repositories_include.rb#L59. So the possible fix would be to call "createSource" from https://github.com/yast/yast-packager/blob/master/src/include/packager/repositories_include.rb#L387 instead of Pkg.SourceCreate here https://github.com/yast/yast-add-on/blob/master/src/clients/add-on_auto.rb#L180
