Installing NIFI 2.0.0 M2 on Ubuntu Linux java.io.IOException: Failed to create Python Environment

[#1]

Hi - I've got everything working with NIFI 2.0.0 M2 when the the python command line is commented out but I'd like to get it up and running with the python command line uncommented.

nifi.properties file line

nifi.python.command=/usr/bin/python3.11

 nifi-app.log info:

yea I saw that post and finally got it to work by making sure I ran this command on Ubuntu to install venv:

sudo apt install python3.11-venv

After I ran that command, everything started up and stayed up normally for NIFI 2.0.0 M2.
