Systemctl - Failed at step Group spawning

Question

I have a problem with automatic running of service. I would like to run a script after user login. Once I have succeeded, however when I tried to automatize it, I'm getting an error and I can't find a mistake.

Service:

Description=Service desc

[Service]
Type=oneshot
Environment=DISPLAY=:0.0
Environment=XAUTHORITY=/home/albert/.Xauthority
Environment=HOME=/home/albert/
User=albert
Group=albert
RemainAfterExit=true
StandardOutput=journal

ExecStart=/home/albert/.startup-script.sh

[Install]
WantedBy=default.target

location: /home/albert/.config/systemd/user/startup-service.service

permissions: -rw-r--r-- 1 albert albert 306 Jan 2 14:49 startup-service.service

Script

Permissions: -rwxr-x-r-x 1 albert albert 86 Jan 2 13:30 /home/albert/.startup-script.sh

I have called:

systemctl --user daemon-reload
systemctl --user enable startup-script.service
systemctl --user start startup-script

And I'm trying to do it on Raspberry Pi 3. Thanks a lot for pointing me at any direction.

Solution

If somebody has similar problem then just remove User and Group from service file. I don't know why, but without them it works pretty well. So the final working service description is:

Description=Service desc

[Service]
Type=oneshot
Environment=DISPLAY=:0.0
Environment=XAUTHORITY=/home/albert/.Xauthority
Environment=HOME=/home/albert/
RemainAfterExit=true
StandardOutput=journal

ExecStart=/home/albert/.startup-script.sh

[Install]
WantedBy=default.target

I can't do that. I need to run my service as a user.

[JiangHongTiao]

By the '.startup-script.sh' I'm running chrome browser and it's running under the currently logged in user. So the user 'albert' from settings above.

[Folaht]

Disregard my comment. I was able to run it as user as well despite it not explicitly stated, though I don't know how I achieved that.

[JiangHongTiao]

probably it is enough when it's located in user's directory. It's just my assumption I didn't study it in detail. However it's doing what I need, so it's enough :) Thanks for your concern!

I can confirm when using --user services it binds the process to the user owning the service.
