Ah sorry, I was not aware that 15 comes after 42, that feels a bit wrong. :-D I used the link on https://docs.microsoft.com/de-de/windows/wsl/install-manual which still is the version 42, and now also found https://github.com/MicrosoftDocs/WSL/issues/330 which suggest to update for 15. :-) Is there a stable link to 15? As far as I read in mentioned issue, the link in the openSUSE repository is not stable as it gets updated with new builds and old builds get deleted. This is bad for including in scripts then, that provision an openSUSE distribution.
