I'm using Ubuntu 18.04 and trying to install a package named dv-runtime-dev. And to launch remote control, I need to start a service using the command
sudo systemctl start dv-runtime.service
And I got the result as follows
Failed to start dv-runtime.service: Unit dv-runtime.service is not loaded properly: Is a directory.
See system logs and 'systemctl status dv-runtime.service' for details.
Then I run the status command and get the following hint
● dv-runtime.service
Loaded: error (Reason: Is a directory)
Active: inactive (dead)
Note that this .service file exists when the package installed. But this file is located in a folder named dv-runtime.service. In other words, to access this file, the path would be
/lib/systemd/system/dv-runtime.service/dv-runtime.service
So I think it might be the same name of the folder and the file that makes the system confused. I then tried to move this .service file out of the folder or even changed its path, but nothing worked.
I also tried to delete that folder and move the .service file in the .../system/ path. Now by using the command
systemctl list-uint-files --type=service
I can see dv-runtime.service in that list (which previously cannot), but the state is disabled. This time I ran the start service command again, and got
Job for dv-runtime.service failed because the control process exited with error code.
See "systemctl status dv-runtime.service" and "journalctl -xe" for details.
Here I checked the status and the journal using the commands as suggested, and the error information appeared to be
● dv-runtime.service - DV-Runtime service deamon
Loaded: loaded (/lib/systemd/system/dv-runtime.service; disabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Fri 2022-10-28 00:18:31 CST; 892ms ago
Process: 10072 ExecStartPre=/bin/touch /etc/dv-runtime.xml (code=exited, status=217/USER)
and
10/28 00:19:03 zeo-HP-Pavilion-Aero-Laptop-13-be0xxx systemd[10105]: dv-runtime.service: Failed to determine user credentials: No such process
10/28 00:19:03 zeo-HP-Pavilion-Aero-Laptop-13-be0xxx systemd[10105]: dv-runtime.service: Failed at step USER spawning /bin/touch: No such process
It appears that the error has something to do with the user, but I don't know how to locate this user problem. Now I have no idea how to start this service now and I hope somebody could help me. Appreciated with much thanks!
