Nothing shows up on the screen when I type my password

I upgraded to Ubuntu 12.04 LTS and was trying to update software with sudo apt-get .... In the Terminal I am asked for my password but it will not accept any form of input. I've tried typing it in, as well as pasting from the clipboard. What should I do?

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.

Remember that the terminal WONT echo back asterisks for characters in your password. If you know that and you are completely sure that you put in the right password (for a user with sudo priviledge): try a different terminal (perhaps the one at alt+ctrl+F1). You can also use GUI sudo (for example gksudo). As soon as your system is up to date check if the problem is still present and if it is -- report a bug. – Krzysztof Hasiński May 9 '12 at 23:06

When you use the Terminal and you need to enter your password, it will not show on the screen at all, this is normal practice.

When the terminal asks for your password just type clear without caps lock on. Note that the password is the same as our Ubuntu login password.
