I see this issue in focal. Nothing happens if I try to enable or disable a source in the "Other Software" tab by clicking a checkbox. I get the same error message as mentioned in comment #2 if I start software- properties-gtk in terminal.
Adding or removing sources works, but not enabling/disabling them. ** Tags added: focal -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1727908 Title: Software & Updates application does not permit changes on the "Other Software" tab To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1727908/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
