Linux

Hello guys!

I'm experimenting with Reticulum at the moment and I've setup a stationary node on a Raspberry Pi 4. So far, it works very well. Now, I ran into a problem with creating a systemd-service for the application nomadnet.

I'm logging in via SSH and user 'admin'. nomadnet has been installed via pipx install nomadnet and can be started with nomadnet, which seems to work very well too. The executable can be found under /home/admin/.local/bin/nomadnet

My goal is: I want the application to keep running, when I'm closing the SSH-connection.

Right now, I'm not very experienced with systemd, but I've asked AI for some help (probably not a good idea...?):

[Unit]
Description=Nomadnet Service
After=network.target

[Service]
Type=simple
ExecStart=/home/admin/.local/bin/nomadnet
Restart=on-failure
User=admin
Group=admin

[Install]
WantedBy=multi-user.target

The nomadnet.service is now running, but when I take a look at journalctl -u nomadnet there seems to be an error loop:

I don't have an idea, how to do it properly, but hopefully, someone can help me here :(.
