Bug description:
[ Impact ]
* On Ubuntu Mate with the Lunar series, when running
ubuntu-release-upgrader, the displayed font of running
applications (including the upgrader) becomes very corrupted.
* This is not just a display problem, it is also a functional one.
The release upgrader will have text corrupted to the point
where a dialog asks a decision, and displays two buttons, but the
text is unreadable and one has to guess which button is the one
that carries out their desired action.
* In the early parts of the upgrader tool, users are told in bold:
"To prevent data loss close all open applications and documents."
This is just before the "Start Upgrade" button is available.
But they may not do so. Many applications may have a corrupted
font.
* To address this, an additional environment variable is being
passed along to pkexec, XDG_CURRENT_DESKTOP, as this is the
critical criteria for making the Mate version of the fix work.
* Also in the change are
* an update to tests
* from pre-build.sh
* an update of the mirrors.cfg, adding and removing several
mirrors
* a refresh of the po files
[ Test Plan ]
* acquire an Ubuntu Mate environment running Ubuntu Lunar on amd64
* as user, run "update-manager -d"
* monitor the "Distribution Upgrade" screen. During the "Installing
the upgrades" step (and mind that this step will be long), observe
the text of the "Distribution Upgrade" screen and verify that the
font does not corrupt.
* Repeat the above for Ubuntu Desktop
[ Where problems could occur ]
* We are changing, at release time, ubuntu-release upgrader. If we
are careless, we could regress upgrades for a wider group of users
than just Ubuntu Mate. That said, it is believed that passing the
additional XDG_CURRENT_DESKTOP variable is relatively low risk.
[ Other Info ]
* TBD

Original description:
I was upgrading from Lunar to Mantic the other day and left a couple
of applications open during the upgrade process. During the upgrade
the text in audacious became unreadable (I'll attach a screenshot) and
I seem to recall the title bar of Firefox being unreadable but the
contents of web pages still being readable.
