Nothing shows up on the screen when I type my password

I have been trying to run [sudo lshw] but it asks [password for grace: [] ]
So when I try to type my password, it doesn't even come up with any letters, asterisks not does the [] move. I typed in my password as normal despite this and pressed [enter] but it just said,

[Sorry, try again.
Enter password for grace: [] ]

But I can't type it in?! Can anybody help?

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.

That's normal behaviour of sudo. Sudo will never give any feedback on the user's input, except for the cursor not blinking while you are typing.

when something is flagged for closure (or voted as it is in this case) adding half or non-answers just breaks the redirection if the question is closed –  hbdgaf Jul 19 '12 at 21:59
Please delete this answer for the greater good of the community (See aking1012's comment above for why). –  izx Jul 19 '12 at 22:00
So how can I if tell a question has been flagged for closure? I don't see a sign anywhere. This site is confusing. –  Cumulus007 Jul 19 '12 at 22:03
@Cumulus007 You probably couldn't have, because there were probably no close votes when you were composing your answer. Your answer was posted very shortly after we close-voted. –  Eliah Kagan Jul 19 '12 at 22:07
Alright, I will be more vigilant from now on. Thanks for the explanation. –  Cumulus007 Jul 19 '12 at 22:08
