Minor storage drive or filesystem errors can also cause the error in question. To set the correct permissions on it, use the chmod command as follows. To check the permissions on this file, use the following command. Wrong permissions on the /etc/shadow file, which stores actual passwords for user accounts in encrypted format can also cause this error. To fix this error, you need to mount the root partition as as read/write as shown. You might also see this error if the / partition is mounted as read only, which means no file can be modified thus a user’s password can’t be set or changed. rw-r-r- 1 root root 896 password-auth-acįor instance a mis-configured /etc/pam.d/common-password file can result into this error, running the pam-auth-update command with root privileges can fix the issue. Lrwxrwxrwx 1 root root 16 password-auth -> password-auth-ac
rw-r-r- 1 root root 659 fingerprint-auth-ac Lrwxrwxrwx 1 root root 19 fingerprint-auth -> fingerprint-auth-ac The various settings for PAM are found in /etc/pam.d/. This makes the module unable to obtain the new authentication token entered. Another possible cause of the “ passwd: Authentication token manipulation error” is wrong PAM ( Pluggable Authentication Module) settings.
