new OS, new problem. :(

Depending on what exact configuration of packages/versions I have I get different error messages. The current one is:

Traceback (innermost last):
  File "/home/lucas/forest/miniconda3/envs/mnemo/bin/mnemosyne", line 4, in <module>
    __import__('pkg_resources').run_script('Mnemosyne==2.9', 'mnemosyne')

The only thing I can say is that the problem lies with your installation of QtWebEngineWidgets, but I guess you also came to that conclusion :-) However, this is not a Mnemosyne problem, but a Ubuntu one, so I'm afraid you have to get in touch with the Ubuntu developers. Just a single-line Python file containing   'from PyQt5 import QtWebEngineWidgets' will be enough to trigger this issue.

Uninstalled the manually installed version (by removing the conda environment). And installed the native Ubuntu 22.10 version which, surprisingly, now seems to be WORKING FINE!
There is just one warning about Google translate not being installed:
usr/lib/python3/dist-packages/mnemosyne/libmnemosyne/__init__.py:377: UserWarning: google_trans package is not installed. Google translate feature will not be available.
  warnings.warn("google_trans package is not installed. Google translate feature will not be available.")

I just solved that by a) installing the python3-pip package and b) installing the googletrans package (pip install googletrans).

Thanks to the holy Gods of Ubuntu!
