Error with addon boot_select. How do I remove from config?

[ThommyaVV]

What type of installation are you running?

Desktop

Which Linux OS are you using?

Arch Linux x86_64

Which version of LNXLink has the issue?

2024.1.0

The problem

running lnxlink -c config.yaml gives me an error with boot_select addon. It gives the error with or without the visudo edit. I'm perfectly willing to remove the addon (I'm also willing to remove any other addon or command). I would like some help understanding the error and how to remove the addon. And I'm also wondering how relevant the connection refused error is.

[Errno 111] Connection refused

Any help appreciated

Usually all users have read access to the grub.cfg file, so if you want to use this addon you should change it's permissions and restart LNXlink.

chmod +r /boot/grub/grub.cfg

At the setup documentation, it is explained how to exclude modules, but this is an example of some modules that I would suggest disabling:

exclude:
  - audio_select
  - bash
  - battery
  - boot_select
  - brightness
  - fullscreen
  - gpio
  - gpu
  - idle
  - inference_time
  - keep_alive
  - media
  - mouse
  - network
  - notify
  - power_profile
  - screen_onoff
  - screenshot
  - send_keys
  - speech_recognition
  - systemd
  - webcam
  - xdg_open

EDIT:
I just saw the Connection refused error.
For that you will have to write the correct credentials to connect to the MQTT broker.
You should check the server, port, user, pass and tls configuration values.

Thank you very much sir

If you don't mind, what is the file name of the config file? On arch I have to use pipx, and it uses a different install location I belive.

[Vasilis Koulis]

The config file is created at the location you run the lnxlink command.
If you don't remember on which directory you started it, you can find it from the systemd service as explained on the documentation:

cat ~/.config/systemd/user/lnxlink.service | grep -i ExecStart

[Vasilis Koulis]

On the 2024.2.0 version, the boot_select module will check if the necessary files exist and it won't affect the normal run of the app if they are not found.
