I am hitting the same problem in Kubuntu 23.10 mantic, after performing the release upgrade.
kubuntu-settings-desktop is marked as conflicting with desktop-base, which is also causing it to be incompatible with a bunch of other important metapackages such as task-desktop and task-kde-desktop. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kubuntu-settings in Ubuntu. https://bugs.launchpad.net/bugs/2025658 Title: Missing Conflicts: desktop-base To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kubuntu-settings/+bug/2025658/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
