Linux: Resetting a user’s password

Q. How do I reset a user's password under any Linux distribution from command prompt?

A. To reset a user's password, use passwd command. You have to change it to a different password.

Login as the root user

Open terminal or shell prompt

Type the following command:
# passwd username
For example, reset a tom's password, enter:
# passwd tom
Type a new password twice.

    I have run into an issue with forcing a user to change their password on first login onto a server where the user logs onto the server they are asked to enter their old password, then the new one. When they enter the new one, no matter what password they use, an message appears that states their password is a dictionary word and will not let them change it.
    Is there a way to fix this??

    I am not able to change the password, and since i cannot update (cause i need the password) I’m pretty much stuck, I got this laptop as a gift and the person who gave it to me forgot the admin password, and he deleted all updates and such, it’s so bad that not even flash player from adobe is installed, I need urgent help. I tried the things above but i am not able to type after i finally get to change the password, it just says its a token error. HELP
