Bug#987656: flent-gui fails to start (ModuleNotFoundError: No module named 'qtpy')
Package: flent
Version: 2.0.0-2
Severity: important
X-Debbugs-Cc: jlsan...@protonmail.com
flent-gui fails to start. I expected a window to appear but nothing happens.
Running 'flent --gui --verbose --debug-error' outputs the following:
Started Flent 2.0.0 using Python 3.9.2.
ERROR: Unable to find a usable Qt version.
Traceback (most recent call last):
File "/usr/share/flent/flent/gui.py", line 68, in
import qtpy
ModuleNotFoundError: No module named 'qtpy'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/share/flent/flent/__init__.py", line 55, in run_flent
from flent.gui import run_gui
File "/usr/share/flent/flent/gui.py", line 93, in
raise RuntimeError("Unable to find a usable Qt version.")
RuntimeError: Unable to find a usable Qt version.
After doing a quick search for 'qtpy', I came across the python3-qtpy
package and installed it. flent-gui now starts as expected.

Ah, looks like the "Recommends" needs to be updated to python3-qtpy
instead of python3-pyqt5; will fix and push an update... Thank you for
the report!
