Title:
  migrate old Qt.Foo names to Qt.Enum.Foo for PyQt6 compatibility

Status in software-properties-qt package in Ubuntu:
  New

Bug description:
  On Lubuntu 25.04, when I launch “Software & Updates” (software-
  properties-qt) under PyQt6/Qt6, the mirror-selection dialog
  immediately crashes with Python AttributeError messages. This prevents
  me from changing my download mirror in the GUI.

  Steps to reproduce:

  Install Lubuntu 25.04 and ensure software-properties-qt is at version
  0.111.

  Install PyQt6 (e.g. sudo apt install python3-pyqt6).

  Run sudo software-properties-qt from a terminal.

  Observe the traceback:

  pgsql
  Copy
  Edit
  AttributeError: type object 'Qt' has no attribute 'AscendingOrder'
  followed by similar errors for MatchExactly, WindowModal, BlockingQueuedConnection, etc.

  Actual behavior:

  The tool crashes before showing any mirror options, printing a Python
  traceback about missing Qt enum attributes.

  Expected behavior:

  The mirror-selection dialog should open normally, list available
  download servers, allow me to sort and select one, and then reload the
  package lists.

  Environment:

  Lubuntu 25.04 (AMD64)

  software-properties-qt 0.111

  Python 3.12

  PyQt6 / Qt 6.5

  Regression:

  Worked correctly under PyQt5/Qt5 in earlier Ubuntu/Lubuntu releases.

  Workaround:

  I manually edited DialogMirror.py to replace old enum references
  (Qt.AscendingOrder, Qt.MatchExactly, etc.) with the new Qt6 scoped
  enums (Qt.SortOrder.AscendingOrder, Qt.MatchFlag.MatchExactly, etc.),
  plus added the missing PyQt6.QtWidgets imports.

  Please update the Ubuntu package so that software-properties-qt is
  compatible out of the box with PyQt6/Qt6.
