I believe the documentation at this page is incorrect for setting vikunja up as a systemd service.
It contains the following
WorkingDirectory=/opt/vikunja
ExecStart=/usr/bin/vikunja
and I think it should be something like
WorkingDirectory=/etc/vikunja
ExecStart=/opt/vikunja/vikunja
It should work if you followed the steps before the systemd file: Install Backend | Vikunja
Vikunja itself looks for a configuration file in various places by itself so the working directory doesn’t really need to be configured. Not sure if it is needed at all in the config, but I don’t know much about systemd.
Ah, I see what you’re saying. Those steps place the binary file in a different location than where it goes with the debian dpkg method. I should have noticed that.
Yeah the deb package needs some work to unify it better with the
systemd file of the rest of the docs.
