I have this authentication required prompt that keeps coming up in a 20.04.2 install. I'm not sure which application or service is causing it to trigger but when I enter my password and press authenticate it goes away. Sometimes it comes back again and not knowing why it is showing up is frustrating. Another inconvenient behavior is that when I leave the computer and return it will sometimes be on the desktop but the "Cancel" and "Authenticate" buttons will not work so there is no apparent way to get rid of it besides rebooting my computer. It's like the process that created the dialog is no longer handling user input but the dialog is still present and in the way.

I believe this is my gs extensions: enter image description here Desktop Icon's by rastersoft appears to be the only one enabled?

james@james-NUC5i5MYHE:~$ gsettings get org.gnome.shell enabled-extensions
@as []

From my Logs program here are the important log messages that appear after launching:

12:39:24 PM gdm-session-wor: gkr-pam: unable to locate daemon control file
12:39:12 PM bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
12:39:10 PM kernel: usb 2-4: 3:1: cannot get freq at ep 0x84

12:39:05 PM systemd-udevd: /etc/udev/rules.d/79-scanner.rules:1 Invalid key/value pair, ignoring.

If someone can advise how to report and maybe disable this that would be helpful.

just resuming the workaround that worked for me, taken from some comments, thanks to Levente and the other contributors.

alt+F2 then r Enter

It restarts the Gnome Shell, getting rid of the "ghost" popup.
In my case, all the other applications and windows didn't have any side effects.

Here's the link to the official bug: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1824874
