updated my password but now system does not recognize new sudo password

Greetings and thank you for your time. I need help with this problem.

So I set up whonix on virtualbox and followed the steps to change passwords (from changeme to new one).
Yesterday I attempted to do a sudo command and my password was not recognized.

I then tried to boot with init = /bin/bash and changed the password again. This time I wrote it down on a piece of paper, typed it one letter/number at a time and kept it easy.
Although the system told me my unix password was updated with success…the damn password is STILL not accepted?

I am at the end of my rope with this one.

Figured out my problem

mount -rw -o remount /

passwd user (added user as that is the default name on whonix)

and the damn thing worked!
