Ubuntu – How to accept the configuration screen that pops up when installing Postfix

postfixsoftware installation

I was trying to install postfix on Ubuntu 11.10 for SMTP support… I typed

sudo apt-get install postfix

and then the installation started.

But during installation a configuration screen popped up which requested me to select an option. Now the problem is that there is no link to accept an option in the configuration screen, and as I can't select an option the installation process stalls.

If i exit the terminal and again try to re-install i get a message

could not get lock /var/cache/apt/archives/lock -open(11. resource temporarily    unavailable)

Screenshots of the problem:

This is similar to this question for accepting an agreement in a debconf question.

 ⇆ TAB , then return ↵ will let you continue.
