I know this is Ubuntu bug reporting tool, but I have the same problem on Fedora. I didn't find this bug reported on Fedora (I'll report it), but I'd like to add some observations for you, so maybe someone will be able to solve this annoying issue. I use Yubikey to login to my Gnome desktop. Everything works fine until I run any program as root (e.g. virt-manager, disks). Then I'm asked to touch my Yubikey to authorize and to run the program as root. So far good. But then I lock the screen (or it locks itself after 5 minutes). When I unlock the screen by touching the Yubikey I see the annoyuing dialog with message "System policy prevents management of the local virtualized systems". I've checked /etc/pam.d/polkit-1 if it uses Yubikey for authentication
#%PAM-1.0 auth include system-auth account include system-auth password include system-auth session include system-auth and /etc/pam.d/system-auth contains auth required pam_env.so auth required pam_faildelay.so delay=2000000 auth sufficient pam_fprintd.so auth sufficient pam_u2f.so debug=1 auth sufficient pam_yubico.so id=1 debug=1 ... Login and other PAM modules use system-auth config as well. So I'd expect that polkit should work with this. But it doesn't. Maybe it need more configuration in other pam sections (account, password, session). I'm not PAM expert. I hope this will help someone to find a fix. -- 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/1824874 Title: undismissable, unclickable authentication dialog left on screen (top- left corner) after policykit authentication [pushModal: invocation of begin_modal failed] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1824874/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
