I changed the maintaina.com Horde Images to use openSUSE Leap 15.2 instead of openSUSE Tumbleweed as a base. You should not experience any issues but I have not yet tested much. The change was necessary as I had build failures since 2021-02-17 in the github actions CI builds. It’s something about the docker used in ubuntu-latest being too old or github’s security settings being too strict. I did invest some weekend hours, but could not really solve it. I intend to switch back to tumbleweed at some point.

Update July 2021: I can now build tumbleweed-based images again.
