Hmm. I'd start with: $ which python3 $ dpkg -S `which python3` and from inside Python: >>> import sys; sys.path >>> import enum; enum.__file__ My best guess at the moment is that your "enum" package is actually a compatibility shim for earlier Python versions, less functional than the one provided by Python 3.7. You may need to *uninstall* a shim package. But I could well be wrong, and maybe there'd be a clue in your paths. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
