    Re: Probleme about changing password

    Hello and welcome to the forums

    "authentication token Manipulation error" usually means the system can't write the new password hash to the shadow file

    If you are using the recovery shell, make sure that you remount the filesystem in read-write mode before trying to change the password:

    mount -o rw,remount /
