CLI commands and GUI not functioning in Ubuntu 24.04

[Sk8teb0arder]

Root privileges required to activate GPS, SDR, USB and LORA, which unfortunately means this script does not work for Ubuntu Rex Image. Would greatly appreciate if this could be remedied.

Do you have any further info? This was entirely developed on the Rex image so it's confirmed working here.

The GUI functionality is not usable in Ubuntu due to root privileges needing to be scripted into the app.

Just seen this response. Did running any steps using sudo help you resolve this issue? Feel free to keep me posted. :)

Vibe coded the following with Claude and it works well.

Here's a summary of everything that was needed to get it working:

1. Wrong Python interpreter
   The system was defaulting to /home/user/.pygpsclient/bin/python3 (a virtualenv) which couldn't see the system gi module needed by pystray. Fixed by always calling /usr/bin/python3 explicitly.
2. Missing AppIndicator backend
   Ubuntu 24.04 with GNOME requires the AppIndicator protocol for tray icons. Fixed with two things:

sudo apt install gir1.2-appindicator3-0.1 libappindicator3-1
os.environ.setdefault("PYSTRAY_BACKEND", "appindicator") added to the script before importing pystray

3. pystray not installed for system Python
   bashsudo pip3 install pystray pillow --break-system-packages
4. aiov2_ctl requires root
   The binary silently printed Must be root and exited 0, so the script thought it succeeded. Fixed by adding sudo to all subprocess calls and adding a passwordless sudoers rule:
   bashecho 'USER ALL=(ALL) NOPASSWD: /usr/local/bin/aiov2_ctl' | sudo tee /etc/sudoers.d/aiov2_ctl
   sudo chmod 440 /etc/sudoers.d/aiov2_ctl
5. Autostart desktop entry
   Updated ~/.config/autostart/HardwareToggle.desktop to use /usr/bin/python3 instead of the venv Python, and removed sudo from the Exec line (the script handles elevation internally).
