I have installed gsettings-desktop-schemas 42~rc-1ubuntu3 from the release pocket, and the dark theme migration took place. All of my applications are now consistently dark themed again, including gnome- disks, nautilus, calculator and calendar. When swapping from light to dark, the change is always applied, and is consistent everywhere.
This issue is resolved, happy to say verified. ** Changed in: gnome-control-center (Ubuntu Jammy) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1965067 Title: [42beta] (some) GNOME applications use light theme when dark is set in gnome-control-center To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1965067/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
