Systembridge going offline

[aniceberg]

I see that Systembridge keeps going offline after a while on my RPi.

I grabbed the systemctl status and got the below python code errors if this is helpful for diagnosing the issue. Are there other logs I should be pulling up to further diagnose the issue and which ones?

Same thing happening with 3.11.2, it starts and shuts after a few seconds

Please update to the latest version of python. 3.9 is no longer supported

[timmo001]

Using the binary is the simplest way to use system bridge. See the installation docs here:

https://system-bridge.timmo.dev/docs/install

[aniceberg]

Thanks. Any idea which binary release would run on a RPi 4 running Raspian Buster, a distro based on debian?

[aniceberg]

Here is my issue-- AFAIK, there's no binary that runs on Raspbian Buster/Bullseye which I can run using the elevated privileges that Systembridge requires on the host machine.

When I go the Python route, I can install it (python -m pip install --upgrade systembridgeshared systembridgebackend systembridgecli) and run it (/usr/bin/python -m systembridgebackend --no-gui) without issue however if I send a keypress I get this in the log:

2023-11-27 10:07:02 INFO (MainThread) [systembridgebackend.server.websocket.WebSocketHandler] Received: KEYBOARD_KEYPRESS
2023-11-27 10:07:02 ERROR (MainThread) [systembridgebackend.server.websocket.WebSocketHandler] You must be root to use this library on linux.

However I don't know how to run python as the root user- because when I attempt that, I get this message:

sudo /usr/bin/python -m systembridgebackend --no-gui
/usr/bin/python: No module named systembridgebackend
[5]+  Killed                  /usr/bin/python -m systembridgebackend --no-gui

I tried installing the python modules under the root user (sudo python -m pip install --upgrade systembridgeshared systembridgebackend systembridgecli) but it gets stuck when trying to install the cryptography module (because of rustc dependencies, which in turn is having issues because it can't find the rustc compiler under the root user.)

  error: rustup could not choose a version of rustc to run, because one wasn't specified explicitly, and no default is configured.
  help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain.
  
      =============================DEBUG ASSISTANCE=============================
      If you are seeing a compilation error please try the following steps to
      successfully install cryptography:
      1) Upgrade to the latest pip and try again. This will fix errors for most
         users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
      2) Read https://cryptography.io/en/latest/installation/ for specific
         instructions for your platform.
      3) Check our frequently asked questions for more information:
         https://cryptography.io/en/latest/faq/
      4) Ensure you have a recent Rust toolchain installed:

As you can tell, I'm not that python or linux savvy in general-- do you have any suggestions or solutions?
