I am stuck in a similar but slightly different situation – but none of the above solved the problem of wmic_server not starting.

The primary visible symptom is following “last message” of the starting server:

“ImportError: cannot import name ‘UUID’ from ‘uuid’ (/opt/commoc/lib/python3/aiowmi/uuid.py)”

Versions:

Ubuntu 20.04
Python3: 3.8.10
gunicorn 20.0.4

The wmic_server.yaml ist the unchanged sample file.

I am stuck with my intellectual abilities here 🙂

Thanks for any help.
