[Bug 1861902] [NEW] Updates via Software Updater after release upgrade to Focal prompt user to run Partial Upgrade

[Cody Shepherd]

Public bug reported:

After completing release upgrade from Eoan to Focal as a devel release
without errors, subsequent updates via Software Updater show a window
that prompts the user for a Partial Upgrade, stating "Not all updates
can be installed.

The user can then either select Partial Upgrade or Continue. Selecting
Continue may or may not upgrade a portion of packages listed (it may
simply state "The software on this computer is up to date"). Selecting
Partial Upgrade requires the user to authenticate, and then prompts the
user to Start Upgrade, with the question "Do you want to start the
upgrade?" as well as details of packages removed, new packages
installed, and packages upgraded. Selecting Start Upgrade installs,
upgrades, and removes packages.

Ubuntu Version: 20.04 Focal Fossa (development branch)
Package version: do-release-upgrade 20.04.9, apt 1.9.8 (amd64)
