At this point, the Qt6 GUI appeared correctly, and I was able to use the
dialog to complete the upgrade normally. The upgrade finished without
errors, and I successfully rebooted afterward. Please see the attached
screenshot for a quick show of the upgrade dialog.

Title:
[SRU/RC] ubuntu-release-upgrader Qt interface Qt6 incompatibility
Status in ubuntu-release-upgrader package in Ubuntu:
Fix Released
Status in ubuntu-release-upgrader source package in Noble:
Triaged
Status in ubuntu-release-upgrader source package in Oracular:
Fix Committed
Status in ubuntu-release-upgrader source package in Plucky:
Fix Released
Bug description:
[Impact]
Qt-based flavors of Ubuntu are unable to upgrade to Plucky from
Oracular or Noble due to the Plucky frontend being ported to PyQt6.
When the port was originally done, the change author actually did test
release upgrades, but failed to consider the fact that additional
dependencies may need to be added. Additionally, the change author
failed to commit a local change, resulting in failing upgrades to
Plucky.
The majority of the required changes will be in Plucky, which will
need review from the Ubuntu Release Team due to freezes. The other two
releases simply need PyQt6 runtime dependencies added.
[Test Case]
We just need to test that an upgrade using the KDE GUI frontend works
on an appropriate flavor of Ubuntu.
First, install ubuntu-release-upgrader-qt from $series-proposed:
$ apt install -y ubuntu-release-upgrader-qt -t $series-proposed
Then, run the upgrade, specifying the KDE frontend to be used:
$ do-release-upgrade --devel --frontend DistUpgradeViewKDE
The upgrade should complete without errors, and the GUI should be
active and usable throughout the upgrade.
[What could go wrong]
While this change was thoroughly tested prior to uploading to Plucky,
it is entirely possible that wider testing of the fixes will reveal
further room for improvement. This falls under the criteria of a bug
fix to a release still in development, and would also be acceptable to
fix past Final Freeze if another problem were to emerge.
When it comes to Oracular and Noble, adding runtime dependencies that
would already be generally common on a Qt-based flavor anyway (when
installing some extra packages) is *almost* a no-op. This being said,
if we were to change the binary package names for pyqt6 in a stable
release update, or if those packages become uninstallable or otherwise
unusable, this change would regress.
[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.
