Since I propose yet another SRU, I created bug #2039356. This bug report is quite noisy already...
My examination of the flavors with respect to this issue focused on two questions: 1. Does the u-r-u model effectively prevent 'the unreadable text issue' when the desktop font in use — whether default or set by the user — has changed during the cycle? After the changes proposed via bug #2039356 I would say "yes" for: Ubuntu Desktop Ubunu Budgie Ubuntu Cinnamon Ubuntu Kylin Ubuntu MATE Ubuntu Unity while the model (i.e. temporarily changing a dconf value which represents the desktop font) is not effective for: Kubuntu Lubuntu Xubuntu In case of Kubuntu and Lubuntu the Qt way of dealing with fonts seems to require something else, and the Xfce way applied in Xubuntu means similar difficulties. Fortunately all those flavors use a desktop font by default (Noto Sans) which was not changed during the cycle, so this does not need to be addressed for mantic. But if you like, you can trigger the 23.04 -> 23.10 upgrade issue in for instance Xubuntu: Go to Settings -> Appearance -> Fonts and change the "Default Font" from Noto Sans to Ubuntu. Doing so will be reflected both in the ~/.config/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml file and in dconf (gsettings get org.gnome.desktop.interface font-name), but changing the font-name dconf value only to something else during upgrade (as we do) won't change the effective desktop font in Xubuntu, which results in 'the unreadable text issue'. 2. Is the temporary desktop font dconf value properly reset at next login after reboot? Yes it is, after the changes proposed via bug #2039356. -- You received this bug notification because you are a member of Ubuntu Touch seeded 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: Fix Committed Status in ubuntu-release-upgrader source package in Jammy: Fix Committed Status in ubuntu-release-upgrader source package in Lunar: Fix Committed Status in ubuntu-meta source package in Mantic: Fix Released Status in ubuntu-release-upgrader source package in Mantic: Fix Committed 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.
