I have been working on trying to run edX master on Ubuntu 20 and using Python 3.8. I have been able to run through the Ansible playbooks to get the code deployed, but I have not yet managed to get to a functional system.
Of note:
- the static assets do not get generated properly. When I try to run the
/edx/bin/edxapp-update-assetsscript I see a sequence of tracebacks at the beginning of execution.
Unable to load XModuleDescriptor 'course'

- Related to this I see log output that is throwing tracebacks due to a lack of the webpack stats file being generated.

- When I try to run migrations I am seeing exceptions about invalid credentials, because for some reason it is trying to use the values for the separate CSMH database (Courseware Student Module History). If I remove the configuration block in
/edx/etc/lms.ymlfor that database then migrations can run through properly, but there is definitely some confusion happening as far as which credentials to use for which database when executing migrations.
I will update this thread with any other findings or changes in state as I periodically attempt to get this build to succeed.
