Error while calling MQTT plugin

[BozoLord]

Hi

I'm running Octoprint on a pi4 (Version 1.8.7) Version 1.0.0, running on Raspberry Pi 4 Model B Rev 1.4

my broker is mosquitto on my home assistant

I've installed mqtt plugin but it's not launching

Here's the logs:

2023-03-06 09:11:59,607 - octoprint.plugin - ERROR - Error while calling plugin mqtt

i've tried installing trhough ssh but it doesn't work either

how could I fix it ?

This truly is a strange error. What it is complaining about is definitely in the docs for the six module.
