I've run into this problem on Trixie and I think it deserves a fix in trixie-updates. I've made a configuration file /etc/mumudvb/mumudvb.conf to my liking and tried to do 'systemctl start mumudvb', but I get https://bugzilla.opensuse.org/show_bug.cgi?id=1196795#c2 Furthermore, systemd separately warns me about this line in the service file: I can't grasp the upstream VCS history, but I think the current service file is supposed to be, approximately, this: https://github.com/braice/MuMuDVB/blob/mumudvb2/scripts/debian/lib/systemd/system/mumudvb.service which isn't afflicted by any of the foregoing issues.
