Thanks. Those repeating errors might be related to the main problem, although it's never certain.
At this stage I would ask you to report the problem to upstream at: https://gitlab.gnome.org/GNOME/gnome-shell/issues However it might be more helpful to wait until Ubuntu 20.04 is released and you have tried that. Then report the bug if it still occurs there. Once you have reported a new issue upstream please tell us the issue ID here. ** Package changed: update-manager (Ubuntu) => gnome-shell (Ubuntu) -- 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/1831332 Title: Huge stack of credential dialogs when switching user To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1831332/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
