Self hosted runner service does not start automatically on Linux Mint

[Edvinas01]

Describe the bug
After configuring the runner as a service on Linux Mint, it doesn't automatically start after the system restarts.

To Reproduce
Steps to reproduce the behavior:

1. Setup Linux Mint 21.3.
2. Follow steps to install the runner as described here.
3. Configure runner as a service as described here.
4. Restart the system.
5. Check journalctl logs, the runner fails with status=203/EXEC.
6. Adjust service file to include /bin/bash in ExecStart.
7. Run systemctl daemon-reload.
8. Restart the system.
9. Check journalctl logs, the runner fails with status=200/CHDIR.

Expected behavior
The runner service automatically restarts with the OS without any errors.

Runner Version and Platform

• Version of your runner: 2.316.1
• OS: Linux Mint 21.3

What's not working?

The runner does not start automatically on system boot when following this guide.

Logs

Here are the logs from journalctl -u actions.runner.ORG.USR.service (note, I replaced organization name with ORG, system name with SYS and username with USR).

Before modifying the service file:

-- Boot 37af18b73b884970900d8058454e90ae --
May 14 16:23:03 SYS systemd[1]: Started GitHub Actions Runner (ORG.SYS).
May 14 16:23:03 SYS systemd[967]: actions.runner.ORG.SYS.service: Failed to locate executable /home/USR/Software/actions-runner/runsvc.sh: No such file or directory
May 14 16:23:03 SYS systemd[967]: actions.runner.ORG.SYS.service: Failed at step EXEC spawning /home/USR/Software/actions-runner/runsvc.sh: No such file or directory
May 14 16:23:03 SYS systemd[1]: actions.runner.ORG.SYS.service: Main process exited, code=exited, status=203/EXEC
May 14 16:23:03 SYS systemd[1]: actions.runner.ORG.SYS.service: Failed with result 'exit-code'.

After modifying the service file to include /bin/bash in ExecStart:

-- Boot 182ab4bd9f0a4c4aabcad80f4161a2ed --
May 14 17:16:45 SYS systemd[1]: Started GitHub Actions Runner (ORG.SYS).
May 14 17:16:45 SYS systemd[1]: actions.runner.ORG.SYS.service: Main process exited, code=exited, status=200/CHDIR
May 14 17:16:45 SYS systemd[1]: actions.runner.ORG.SYS.service: Failed with result 'exit-code'.

More Info

1. If I start the service manually via sudo ./svc.sh start it works fine, only when restarting the service doesn't boot up automatically.
2. Service file created by svc.sh (note, I added /bin/bash to ExecStart):

[Unit]
Description=GitHub Actions Runner (ORG.SYS)
After=network.target

[Service]
ExecStart=/bin/bash /home/USR/Software/actions-runner/runsvc.sh
User=USR
WorkingDirectory=/home/USR/Software/actions-runner
KillMode=process
KillSignal=SIGTERM
TimeoutStopSec=5min

[Install]
WantedBy=multi-user.target

3. This is a clean Linux Mint install with just the runner installed and nothing else.
