** Description changed:
+ [Impact]
+
+ Qt-based flavors of Ubuntu are unable to upgrade oracular -> plucky due
+ to Qt6 incompatibility issues. I have done the legwork and refactored
+ the code so that it works.
+
+ [Test Case]
+
+ * From Kubuntu, attempt an upgrade via 'do-release-upgrade -d -m desktop
+ -f DistUpgradeViewKDE'
+
+ Expected: Upgrade interface works.
+
+ Actual: Upgrade fails with multiple Qt incompatibilities
+
+ * Testing the fix requires 'do-release-upgrade -d' from the terminal,
+ and saying "no" at the second y/N prompt. From there, navigate to
+ '/tmp/ubuntu-release-upgrade-{hash}' and add
+ https://git.launchpad.net/~ubuntu-qt-code/ubuntu-release-
+ upgrader/plain/DistUpgrade/DistUpgradeViewKDE.py?h=ubuntu/main to the
+ folder.
+
+ * Additionally, add the following dependencies:
+
+ - pyqt6-dev-tools
+ - python3-pyqt6
+ - python3-pyqt6.qtquick
+
+ * Once that's done, from the `/tmp/ubuntu-release-upgrader-{hash}`
+ directory, run 'sudo -E ./plucky'. The upgrade should function at this
+ point.
+
+ [What could go wrong]
+
+ In my testing in a VM, this failed to bring up a progress window, but
+ also did not fail outright with any errors. That could be the nature of
+ the VM and the testing, but if that's not the case, then further
+ refinements may be required.
+
+ [Original Bug]
+
This is likely an issue RE: Qt5 vs Qt6. I have reason to believe the
code is still Qt5 but oracular and higher is Qt6, meaning the code needs
to be refactored.
