Hopefully an ubuntu-release-upgrader workaround will be in place soon. But in a sense this is an ubuntu-meta matter as well. The code in my merge proposal sets the "Sans" font temporarily, which in lunar means that either DejaVu Sans or Noto Sans will be used in the UI during the upgrade (unless the user has configured fontconfig to use some other font...). And that is fine in lunar, since DejaVu Sans is always present, and neither DejaVu Sans nor Noto Sans were changed during the mantic cycle.
But one of the changes in mantic is that no font is safely present (i.e. the default ones are "Recommends:" only). So later, when people will upgrade from 23.10 to 24.04, just using "Sans" temporarily may not be the best option. And changing it to a specific font family is tricky, since we don't know if the user has uninstalled some of the default font packages. So my thought is: Can this be a reason to let desktop-common depend on, and not only recommend, some font package after all? And if so, which package would be suitable for the purpose? -- 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.
