Trouble upgrading from Python3.6 to Python3.9

Help
1

I am trying to troubleshoot an error with Librenms.
When trying to access the WebUi, I get the classical " Whoops, looks like something went wrong. Check your librenms.log."
My platform:
Description: Ubuntu 18.04.5 LTS

My output on ./validate.php shows:

====================================
Component | Version
--------- | -------
LibreNMS | 21.6.0
DB Schema | 2021_02_09_122930_migrate_to_utf8mb4 (204)
PHP | 7.4.20
Python | 3.6.9
MySQL | 10.5.10-MariaDB-1:10.5.10+maria~bionic
RRDTool | 1.7.0
SNMP | NET-SNMP 5.7.3

I am currently trying to update Python from 3.6.9 to 3.9.5 and all of the installation progress seems to be fine and dandy, but when i run ./validate it shows 3.6.9 still. And yes, I have rebootet after installing. Any suggestions on how to fix this?

Because it’s probably the default version for your python3 command. Why not just update to ubuntu 20.04 and you get all required softwares and a more modern OS.

Yes, I was thinking that might help, but I also noticed some trouble by upgrading to 20.04 while running LibreNMS on it.
My biggest concern is to have to rebuild the entire LibreNMS-setup that I have running here.
Can anyone lead me in the direction of a guide that might help?
I understand that it is not given that a guide will guarantee me not messing up, of course.

Uninstall python 3.6 if you’re not using it
