In both Vanilla Emacs 22 and 23 CVS
 (require 'tramp)
 (shell-command "sudo touch ~/.emacs")
fails with the message
 sudo: no tty present and no askpass program specified

What is missing?

Using M-! and typing "sudo ls" into the minibuffer, I see the same
error message with Emacs 23.1.1 on OpenSuse.  Mac OS X displays a
password prompt in the minibuffer, but the password prompt doesn't
seem to accept focus (emacs 22 and 23).

What I really want to do is to spawn an install using apt-get install
from within emacs.

Try this.

 M-x shell

Then run "sudo apt-get install" from the *shell* buffer.  You should
get a password prompt in the minibuffer.

(FWIW, I thought this was one of the neatest additions in Emacs 22 :)
