Dear list,
I want to compile (C-c C-c) the following code

#+begin_src sh
sudo apt-get update
#+end_src

The following warning/error appears in the Org-Babel Error Output:
sudo: sin tty presente y no hay programa askpass especificado
sudo: sin tty presente y no hay programa askpass especificado
Sorry, try again.
sudo: sin tty presente y no hay programa askpass especificado
sudo: sin tty presente y no hay programa askpass especificado
Sorry, try again.
sudo: sin tty presente y no hay programa askpass especificado
sudo: sin tty presente y no hay programa askpass especificado
Sorry, try again.
sudo: 3 intentos de contraseña 

The translation is "sudo: no tty present and no askpass program specified"

How should I configure Org mode or my system to run this chunk?

I am running ppa:cassou/emacs in Lubuntu: GNU Emacs 24.3.50.1 (i686-pc-linux-gnu, GTK+ Version 3.4.2)
 of 2013-01-01 on nannyberry, modified by Debian

Thanks!
Emilio
