Trying to think in terms of robust general solutions to this problem, what if update-manager were to notice when fonts were upgraded, and when they are, shut down the GUI connection and reinitialize it? This might require saving a bit of state information in update-manager in order to be able to restore it.
Similiar in principle would be for the font libraries to notice when the fonts have changed on disk and react accordingly, but since this obviously hasn't been done yet and this problem has existed for years, we maybe shouldn't count on solving that in the near term. -- 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 ubuntu-meta package in Ubuntu: Confirmed Status in ubuntu-release-upgrader package in Ubuntu: In Progress Status in ubuntu-meta source package in Mantic: Confirmed Status in ubuntu-release-upgrader source package in Mantic: In Progress Bug description: I was upgrading from Lunar to Mantic the other day and left a couple of applications open during the upgrade process.
