The branch has been created (https://github.com/yast/skelcd-control-openSUSE/tree/openSUSE-15_2), I did some updates for 15.2 (https://github.com/yast/skelcd-control-openSUSE/pull/193). Then I did small adaptations on the Jekins side, the automation now works. The job https://ci.opensuse.org/view/Yast/job/yast-skelcd-control-openSUSE-openSUSE-15_2/6/console created a submit request https://build.opensuse.org/request/show/725284. Now you can open pull request with your changes to openSUSE-15_2 as usually.
