Ubuntu 22.04 - Systemd Service scenarios to Start with 'Service how to be started: No such file or directory'
I'm integrating two systems and I need some guidance on I've searched everywhere and can't find a clear answer... Hey everyone, I'm running into an issue that's driving me crazy. I'm trying to create a systemd service on my Ubuntu 22.04 machine to manage a Python script that processes some data continuously. However, whenever I attempt to start the service, I encounter the behavior: `Failed to start myscript.service: Unit myscript.service not found.` I double-checked my service file located at `/etc/systemd/system/myscript.service`, and it seems correctly configured. Here's what the content of the service file looks like: ```ini [Unit] Description=My Python Script Service [Service] ExecStart=/usr/bin/python3 /home/user/myscript.py WorkingDirectory=/home/user/ User=user Restart=always [Install] WantedBy=multi-user.target ``` After saving the file, I ran `sudo systemctl daemon-reload` to reload the systemd configuration, and I made sure the script has executable permissions using `chmod +x /home/user/myscript.py`. However, when I try to start the service with `sudo systemctl start myscript.service`, I still receive the same behavior message. To troubleshoot, I checked the status of the service with `sudo systemctl status myscript.service` and got: ``` ● myscript.service - My Python Script Service Loaded: behavior (Reason: No such file or directory) Active: inactive (dead) ``` I also verified that the Python script is indeed present in the specified directory by running `ls /home/user/myscript.py`, and it returns the correct file. I've read that the question could be due to incorrect paths or permissions, but I’ve checked those multiple times. What else could be causing this scenario, and how can I successfully start my systemd service? My development environment is Ubuntu. Is there a better approach? I've been using Python for about a year now. Has anyone else encountered this?
