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
12:39:08 PM bluetoothd: Failed to set mode: Blocked through rfkill (0x12)
12:39:06 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.

  • That dialog is weird even in its appearance: it's supposed to be on the very center of the screen, with a dark overlay behind it (that cannot be controlled by regular (gnome-shell-)themes). Your gnome-shell seems to have some hiccups. Please update your question with the list of gnome-shell-extensions that you have installed. In the meanwhile, for a quick workaround, try restarting the gnome-shell, like this: askubuntu.com/a/1319534/1157519

  • It normally shows up in the center and operates in that I can cancel or enter my password and authenticate. The image is when I leave the computer alone for a while and come back to a non functional window oddly on the left side of the display.

  • gsettings get org.gnome.shell enabled-extensions Could you edit your question and add the return value of this command? Please put every item on a new line (you can force line breaks in the markdown editor by appending two dangling spaces at the end of the line where you want the break).

  • Also open the app called "Logs", and look on its first screen, called the Important tab. Do you see anything telling in there?

    Ahh, it's written on the dialog: "Authentication is required to refresh the system repositories" I have found a few things when searching that: askubuntu.com/questions/1193810/… and c-nergy.be/blog/?p=14051
