That's weird, ResourcesUpdatesModel::useUnattendedUpdatesChanged() shouldn't be called here since there's nothing in the GHNS window that can affect that. In fact it's not supposed to get called at all unless you manually alter this setting in the KCM. *** Bug 445199 has been marked as a duplicate of this bug. *** *** Bug 445283 has been marked as a duplicate of this bug. *** Same problem in Tumbleweed using factory repositories, so Plasma 5.23.90 - Frameworks 5.90.0 - qt 5.15.2 - Applications 21.12.2.
Starting Discover from the terminal I get :

I think it's the same bug, but I'm not sure, in any case Discover doesn't start.
