Debian 11 - Custom Systemd Service scenarios with 'ExecStart=... has scenarios' on Boot
Could someone explain I need some guidance on I'm performance testing and I'm deploying to production and I'm attempting to set up I've spent hours debugging this and I've searched everywhere and can't find a clear answer... I'm having trouble getting my custom systemd service to start on boot in Debian 11. The service is supposed to run a Python script located at `/usr/local/bin/my_script.py`. I've created a service file at `/etc/systemd/system/my_service.service` with the following content: ```ini [Unit] Description=My Custom Python Script After=network.target [Service] Type=simple ExecStart=/usr/bin/python3 /usr/local/bin/my_script.py Restart=on-failure [Install] WantedBy=multi-user.target ``` However, when I try to enable and start the service, I get the following behavior message in the logs: ```bash $ sudo systemctl enable my_service $ sudo systemctl start my_service $ sudo journalctl -u my_service -- Logs begin at Fri 2023-09-01 12:00:00 UTC, end at Fri 2023-09-01 12:05:00 UTC. -- Sep 01 12:00:00 myhostname systemd[1]: my_service.service: Failed to execute command: Permission denied Sep 01 12:00:00 myhostname systemd[1]: my_service.service: Main process exited, code=exited, status=203/EXEC ``` I have checked the permissions on the script and it is executable: ```bash $ ls -l /usr/local/bin/my_script.py -rwxr-xr-x 1 root root 1234 Sep 1 12:00 /usr/local/bin/my_script.py ``` Additionally, I verified that the shebang line at the top of my script is correct: ```python #!/usr/bin/env python3 ``` I've also tried running the script directly as root from the command line, and it runs without any issues. I ensured that there are no typos in the service file. I ran `systemctl daemon-reload` after making changes to the service file. What else could be causing this `Permission denied` behavior? Any insights would be greatly appreciated. I'm developing on Windows 10 with Python. How would you solve this? I'm on Ubuntu 20.04 using the latest version of Python. Cheers for any assistance! My development environment is Ubuntu 22.04. Any ideas what could be causing this? I'm coming from a different tech stack and learning Python.
