After the last update I can no longer log into my system (KDE). At first it affected only the log in screen (sddm) and I managed to log into TTY.
After choosing “other” and typing my username into the field, password was also accepted.
Sadly I was stupid enough to reboot my system once more and now cannot log in with either method.
Before the reboot i tried to change my password with passwd but received the following error:
passwd myuser
Changing password for myuser.
Current password:
passwd Authentication service cannot retreive authentication info
passwd: password unchanged
I would like to attempt to roll back my system via timeshift.
Am i correct in the assumption that the process for this would be to:
boot from live cd,
chroot into the system,
mount md0 (the raid10 array that holds the system backups (rsync)),
then issue sudo timeshift --restore?
Thanks for your help. Please also feel free to split this off to correct support category.
Cheers Beer!
Update:
After restoring last nights snapshot and dealing with some grub problem which in turn forced me to update the system while reinstalling grub, things are back to normal for now.
Still no idea what may have caused the inital password problem however.
