I'm having this issue as well when running ubuntu 20 containers, back-leveling to ubuntu 18 resolved my problems

This specific error is fixed in the repository, but the pypi package hasn't been updated, so you can install via:

pip install git+https://github.com/coderanger/supervisor-stdout

More accurately, the actual command is:

pip install 'supervisor-stdout @ git+https://github.com/coderanger/supervisor-stdout'

• or -

pip install git+https://github.com/coderanger/supervisor-stdout
