I am unable to change my password even in root (recovery mode), or to unlock it. I can still access my account, but without password protection.
I forgot my Ubuntu password so I booted into recovery and dropped into a root shell prompt and this is what happened:
root@username-PC:~# passwd username
Enter new UNIX password:
Retype new UNIX password:
passwd: Authentication token manipulation error
passwd: password unchanged

Ok..I'll explain what I did wrong, and then what I did to fix, which led me to my current dilemma.
I thought I was going to be a smartypants and change my password to something really easy. Well, I goofed it up. When I tried to log on, I couldn't.
So I accessed the root shell to change password, but encountered " change password authentication token manipulation error".
I'm trying to sign in, log on, but I continually get a box saying password. Not recognized. I noticed in first boot up it mentioned password failed, shadow password would be used instead. I don't know what the shadow password is nor how to change it. I've been into user accounts and tried changing it that way but password is still not recognized. My installation.
