Title:
  [SRU] Dialog not opening after selecting "Other" for Ubuntu Software
  source

  Fix Released
Status in software-properties source package in Plucky:
  Fix Released
Status in software-properties source package in Questing:
  Fix Released

Bug description:
  [Impact]

  Users are unable to select alternative mirrors under Software Sources
  for Kubuntu, Lubuntu, and Ubuntu Studio which use software-properties-
  qt. As it turns out, this is because DialogMirror.py was never ported
  to Qt6.

  [Test Plan]

  Steps to reproduce.

  1) Go to "Software Sources"
  2) Go to "Ubuntu Software" tab
  3) On the "Download from:" field select the option "Other..." in the dropdown.

  Expected result: A dialog opens which allows selecting a mirror and mirror is actually selected and used.
  Actual result: "Software Sources" tab freezes for ~1 second and the dialog is not opened.

  [What problems could occur]

  There may be more issues that could occur, such as other fields being
  incomplete, but this has been well-tested.
