Cannot Change Root Passwd

I know there have been a lot of posts about this, but cannot seem to find an answer that has worked for me.

I wanted to change the password of my root user, but have failed in doing so.

logged in as root; root@ubuntu:/ passwd

passwd: Permission denied

passwd: password unchanged

root@ubuntu:/ sudo passwd root passwd: Permission denied;; passwd: password unchanged;;

this is a ubuntu 10.04 system and i dont know how can i solve this. I have tried changing the PAM files as well as login.defs file,but to no avail. can anyone help me?

Make sure your /etc/pam.d/common-password looks like this

# here are the per-package modules (the "Primary" block)
password        [success=1 default=ignore]      pam_unix.so obscure sha512
# here's the fallback if no module succeeds
password        requisite                       pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
password        required                        pam_permit.so
# and here are more per-package modules (the "Additional" block)
# end of pam-auth-update config

Enter recovery mode through grub and choose to enter a root shell. From there:

passwd <user>

No unmounting of the drive is required.
