Showing following errors for while docker build
Unable to locate package libopenjpeg-dev
ModuleNotFoundError: No module named 'misago.admin.forms'
Need a bit more info here. At least what branch you are using.
Edit: I suspect you are using
master branch. I'm guessing
0.19.x is more relevant.
Another reason for this happening is that you have an old
python:3 docker image. Try adding
--pull parameter the
build command to override local cache. This is related to this commit in master.
