To the extent I participated in the resolution of this bug, I had standard Ubuntu in mind, where the default desktop font can be accessed like this:
gsettings get org.gnome.desktop.interface font-name And that's the key whose value is temporarily changed when upgrading to 23.10. But on MATE that does not help, since MATE uses its own schema: gsettings get org.mate.interface font-name And since MATE uses the Ubuntu font by default, the issue is identical to the issue in standard Ubuntu. I think the fix in ubuntu-release- upgrader can be adjusted so it interacts with the schema which is actually in use in MATE. But this makes me wonder if there is a need to special case other flavors besides MATE. ** Also affects: ubuntu-mate Importance: Undecided Status: New -- 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 Ubuntu MATE: New Status in ubuntu-meta package in Ubuntu: Fix Released Status in ubuntu-release-upgrader package in Ubuntu: Triaged Status in ubuntu-meta source package in Mantic: Fix Released Status in ubuntu-release-upgrader source package in Mantic: Triaged Bug description: I was upgrading from Lunar to Mantic the other day and left a couple of applications open during the upgrade process.
