Issue is occurring on my daughters laptop. Unable to login because ‘password authentication failed’.
We’ve tried starting from a chroot and setting a new password but that’s made no difference.
Looking through the journal:
journalctl -u gdm
We see the last successful login looked like:
started Gnome display manager
gkr-pam: unable to locate daemon control file
gkr-pam: stashed password to try later in open session
pam_unix(gdm-password:session) session opened for user NAME(uid=1000) by NAME(uid=0)
gkr-pam: unlocked login keyring
But the next (and following attempts):
started Gnome display manager
pam_unix(gdm-password:auth) authentication failure; logname= uid=0 euid=0 tty=/dev/tty1 ruser= rhost= user=NAME
gkr-pam: unable to locate daemon control file
gkr-pam: stashed password to try later in open session
gkr-pam: unable to locate daemon control file
gkr-pam: stashed password to try later in open session
gkr-pam: unable to locate daemon control file
gkr-pam: stashed password to try later in open session
Any suggestions for what might be wrong?
And what should we look for in the journal for a failed login on a console?
EDIT: to add, there are several gigabytes free on both / and /home partitions - removed 500mb of thumbnails in /home just in case. Made no difference.
EDIT2: gave root a passwd and can log in as root on the console! Progress, but original problem remains. Still no clue why she can’t login.
