Hello Andrej. A fix for this bug has been committed to salsa some time ago, along with several other fixes. Would be possible to make a release?
Fixing #1110231 (open-build-service: wrong VCS fields) would be nice as well. It looks like the intent is to move the package to the debian namespace, but a confirmation of that would be welcome. In fact, if somebody from the ruby team can confirm that this should now be handled in the debian namespace, I would be willing to do a "team upload for the debian team" and fix the VCS fields at the same time, but I definitely don't want to step on anyone's toes. Thanks.
