Looking at: /usr/lib/python3/dist-packages/compressor/management/commands/compress.py
at the end, we can see: Command.requires_system_checks = falseIf I change this from "false" to just "[]", then everything works. So the issue really is in python3-django-compressor. I'll fix this after this week-end, after Bookworm is released.
