Install virtualenv - getting password key graphic

On ex 46 in lpthw, when I tried to install virtualenv I got the attached and I can no longer type anything in the terminal. Can anyone help me figure out what’s going on here, please?

Thanks for your time!

Once again, I fixed my own problem right after posting in here. Short answer = type in your computer password (duh). For whatever reason, it took a few times for it to take the password. Maybe I got sausage fingers and typed the pw wrong. heh. Commenting here in case anyone has this same dumb issue in the future.

That’s how it always goes. Thanks for coming back and following up with the solution.
