error: legacy-install-failure
Initially, the error seemed to be that I hadn't install the python3 dev tools correctly, so I reinstalled python3. However, I know believe this is an issue with my installation of MySql.
I reinstalled python3 with suggested packages. I also ensured configuration files were added for mysql.
You are in a virtual environment using python 3.9 instead of python 3.8 shipped with Ubuntu 20.04 try :
sudo apt install python3.9-dev
This package installs all headers files needed to build python3.9 instead of 3.8
