[Bug 2154237] [NEW] ImportError: cannot import name 'uic' from 'PyQt6'

[Daniel Tang]

Public bug reported:

I cannot run `software-properties-qt` immediately after apt-installing
it on Kubuntu 26.04.

# Expected behavior

It should not crash

# Actual behavior

```console
home at daniel-desktop3:~$ GDK_BACKEND=wayland software-properties-qt
Traceback (most recent call last):
  File "/usr/bin/software-properties-qt", line 36, in <module>
    from softwareproperties.qt.SoftwarePropertiesQt import SoftwarePropertiesQt
  File "/usr/lib/python3/dist-packages/softwareproperties/qt/SoftwarePropertiesQt.py", line 37, in <module>
    from PyQt6 import uic
ImportError: cannot import name 'uic' from 'PyQt6' (/usr/lib/python3/dist-packages/PyQt6/__init__.py)
```

# Workaround

```bash
sudo apt install pyqt6-dev-tools
```

# Analysis

Please adjust the packaging of python3-pyqt6. Either:
* Soften the hard-dependency on uic
* Merge package pyqt6-dev-tools with package python3-pyqt6
* Add `Depends: pyqt6-dev-tools` to python3-pyqt6's control
