How do I reset a lost Administrative(root) password?

I lost my Ubuntu user account password...

I saw some other questions on this topic that had answers telling me to restart the computer, press the left shift key after BIOS, go to root, type passwd myusername and all this other stuff, but none of that worked. After I typed a new password and retyped it, it gave me an error message saying something like "Authentication Manipulation Error." There was another question complaining about this, but there weren't any useful answers that worked. Does anybody know of a way for me to retrieve or reset my password? Am I doing something wrong with that method I mentioned?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

As you said, you need to hold shift to get boot menu, choose recovery mode. Then you need to mount your partition read/write, or you get the "Authentication Manipulation Error." Choosing to do an fsck will do this, then you can drop to root console and do the passwd username
