cv2.error: OpenCV about deface HOT 5 CLOSED

This looks like an error inside of OpenCV itself. Have you tried different versions of OpenCV? You can also avoid the OpenCV convolution code path by installing onnx-runtime and using that as the backend (see https://github.com/ORB-HD/deface/blob/master/README.md#hardware-acceleration).

I was just trying again, this time with a completely fresh Ubuntu 22.04.01 LTS installation with nothing else installed.

It won't work either, but with a different error:

Apparently the normal opencv package on pypi requires some additional system packages. You can either install them directly (for the current error apt install libgl1 should do the trick but I don't know if other libraries are missing), or follow the official installation instructions here: https://docs.opencv.org/4.x/d2/de6/tutorial_py_setup_in_ubuntu.html

Thank you for your time, I guess this is not really the right place for noob questions from me, haha.
Anyhow, I installed a fresh Ubuntu 22.04 again, first installed OpenCV manually with sudo apt install python3-opencv end then installed deface through pip. Now it runs without any errors.

Will try upgrading my actual server again and try the same route. Anyhow, thanks!

No problem, glad to hear that it works now with the apt installation. Good luck with the server upgrade!
