Public bug reported: (Note that I'm not using the fingerprint reader.)
If you have: - fprintd but not: - libpam-fprintd gdm3/pam refuses login. The following logs are observed at boot: dbus-daemon[1928]: [system] Activating via systemd: service name='net.reactivated.Fprint' unit='fprintd.service' requested by ':1.45' (uid=128 pid=2541 comm="/usr/bin/gnome-shell " label="unconfined") fprintd[2799]: libusb: error [udev_hotplug_event] ignoring udev action change fprintd[2799]: libusb: error [udev_hotplug_event] ignoring udev action change dbus-daemon[1928]: [system] Successfully activated service 'net.reactivated.Fprint' systemd[1]: Started Fingerprint Authentication Daemon. This is seen when a gdm login is attempted: gdm-fingerprint][3012]: PAM unable to dlopen(pam_fprintd.so): /lib/security/pam_fprintd.so: cannot open shared object file: No such file or directory gdm-fingerprint][3012]: PAM adding faulty module: pam_fprintd.so gdm-fingerprint][3012]: gkr-pam: no password is available for user Either removing fprintd or installing libpam-fprintd fixes so you can log in again. Versions: - ubuntu 22.04 - gdm3 42.0-1ubuntu7.22.04.4 - fprintd 1.94.2-1ubuntu0.22.04.1 - libpam-fprintd 1.94.2-1ubuntu0.22.04.1 Cheers, Walter Doekes ** Affects: gdm3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069498 Title: (jammy) gdm3 login impossible with fprintd but no libpam-fprintd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/2069498/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
