This → How to install PsychoPy 2022.1.4 on Ubuntu 22.04 using virtualenv
almost works.
I needed to sudo apt install python3.8=tk and pip install attrdict3 before installing psychopy and wxpython.
Launching psychopy works. Most of the examples work. However movies don’t play and sometimes psychopy hangs.
