Systemd Services Don't Work

[Brando569]

I have a few usenet programs that I downloaded from GitHub and they didn't come with Systemd unit files so I grabbed a few from the net, even after modifying them with the correct arguments none of them work. The strange thing is that if I copy the ExecStart line and paste it into the terminal it runs as expected. They all complain about the same error since they all python scripts.

Here's one for SickRage

[Unit]
Description=SickRage Daemon

[Service]
User=root
Group=wheel

Type=forking
GuessMainPID=no
ExecStart=/usr/bin/python /opt/usenet/sickrage/SickBeard.py -q --daemon --nolaunch --datadir=/opt/usenet/sickrage

[Install]
WantedBy=multi-user.target

Here's the error from journalctl -xe

Python definitely exists and is executable so I have no idea why it's complaining

 [root@odroid /opt]# ls -lh /usr/bin|grep python

Actually it's happening with binary files also.

Problem possibly in

There is no wheel group for Debian based distros, though Redhat based distros have a wheel group.

Change it to

Group=root

Side note: Not a good idea to run processes as root, if they are compromised, they have free reign of the system.

[Brando569]

Changing the group from wheel to root got rid of that error but the services still fail to start.
