I see the bug is addressed, but for what it's worth, one more data point. I just run into the issue today when doing
apt remove fonts-ubuntu* What I didn't notice was that a replacement instead of a removal was carried out fonts-ubuntu (0.83-6ubuntu1 => 0.869-0ubuntu1) After a while I turned back to Firefox — which I had set up to use Ubuntu font as default — and it had corrupted font. That was not during installation, it was my normal several months old Mantic environment. Restarting Firefox solved the problem. I can reproduce it with apt install fonts-ubuntu fonts-ubuntu-classic- ** Attachment added: "zalgo:firefox-right:chromium-left.png" https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/2034986/+attachment/5712410/+files/zalgo%3Afirefox-right%3Achromium-left.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/2034986 Title: some text became unreadable during a distribution upgrade Status in Cinnamon: New Status in Ubuntu MATE: New Status in ubuntu-meta package in Ubuntu: Fix Released Status in ubuntu-release-upgrader package in Ubuntu: In Progress Status in ubuntu-release-upgrader source package in Jammy: Fix Committed Status in ubuntu-release-upgrader source package in Lunar: Fix Released Status in ubuntu-meta source package in Mantic: Fix Released Status in ubuntu-release-upgrader source package in Mantic: In Progress 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.
