Can't run under Ubuntu 22.04

[dwarning]

I tried to install the program under the new Ubuntu release 22.04. I have Qt4 and Qt5 installed.
But got runtime error:
Traceback (most recent call last):
File "/home/dietmar/.local/bin/qspectrumanalyzer", line 5, in

our_submodule = getattr(Qt, name)
AttributeError: partially initialized module 'Qt' has no attribute 'QtGui' (most likely due to a circular import)
Under 20.04 everything was well.

I'm not the developer, but this looks like a conflict between PyQt and Qt.py, which are two different packages. You have Qt.py installed outside the package manager and it's taking precedence over PyQt. Either remove Qt.py, move it to a virtualenv, or run qspectrumanalyzer inside its own virtualenv.

Thanks for response.
I removed Qt.py but then the import can't work:

from Qt import QtCore, QtGui, QtWidgets, __binding__
ModuleNotFoundError: No module named 'Qt'

I have python3-pyqt5 installed. It is a nightmare with the qt installation.

Actually I was mistaken. Qt.py is indeed used by this project, so you need it installed after all. Reinstall it but try using pip install --user Qt.py and see if that works better.

Run python3 -c "import sys; print('\n'.join(sys.path))" to see what library paths are being searched by your Python instance.

Check /usr/local/lib/python3.10/dist-packages/ for any lingering references to Qt that shouldn't be there.
