I use a YubiKey + PIN as my normal authentication method on Ubuntu 26.04. It works correctly for GDM login and `sudo`.
I noticed the problem when launching Input Remapper, which requests elevated privileges through polkit. The polkit prompt falls back to my account password instead of allowing YubiKey + PIN authentication. Since the same `pam_u2f` setup works elsewhere, this appears to be the issue described here: polkit 127 sandboxes its PAM helper so that it cannot access the YubiKey’s `hidraw` device unless the distribution’s `pam-u2f` package supplies the required systemd permissions. Ubuntu’s package currently does not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2148352 Title: Fix authentication with polkit 127+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pam-u2f/+bug/2148352/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
