Can't Install STAI From Source on Linux Mint (21.3)

[WarutaShinken]

Problem

Installing STAI from source on Linux Mint 21.3 results in the following errors:

• E: Unable to locate package python3.9-venv
  E: Couldn't find any package by glob 'python3.9-venv'
  E: Couldn't find any package by regex 'python3.9-venv'
  

• After resolving the first error:

  The virtual environment was not created successfully because ensurepip is not
  available.  On Debian/Ubuntu systems, you need to install the python3-venv
  package using the following command.
  
      apt install python3.10-venv
  
  You may need to use sudo with that command.  After installing the python3-venv
  package, recreate your virtual environment.
  
  Failing command: /path/to/stai-blockchain/venv/bin/python3.10
  

This appears to be due to the fact that Python 3.9 isn't available on Linux Mint 21.3.

Solution

Run these 2 commands, along with making sure your packages repos are up to date and git is installed. Each command resolves their respective error:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt install python3.10-venv

This should be resolved in the next STAI update. Additionally, this update should also work for installing Chia 1.5.0, which STAI 1.3.1 is based on.
