[felix@x1 ~]$ flent --gui --debug
Starting Flent 2.0.1 using Python 3.10.4.
ERROR: Unable to find a usable Qt version.
Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/flent/gui.py", line 87, in <module>
    from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg \
  File "/usr/lib64/python3.10/site-packages/shiboken2/files.dir/shibokensupport/__feature__.py", line 142, in _import
    return original_import(name, *args, **kwargs)
ModuleNotFoundError: No module named 'matplotlib.backends.backend_qt5agg'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.10/site-packages/flent/__init__.py", line 56, in run_flent
    from flent.gui import run_gui
  File "/usr/lib/python3.10/site-packages/flent/gui.py", line 93, in <module>
    raise RuntimeError("Unable to find a usable Qt version.")
RuntimeError: Unable to find a usable Qt version.

Solution: add python3-matplotlib-qt5 to the "Recommends" of the package.
