I didn't actually write the test plan, I edited the other parts and planned on circling back with something lightdm-style, but yes, I'm in agreement here. :)

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] * From Kubuntu, attempt an upgrade via `sudo do-release-upgrade -d -m desktop -f DistUpgradeViewKDE` Expected: Upgrade interface works. Actual: Upgrade fails, sometimes silently * 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] 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.
