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.

Try this command in terminal: sudo dpkg-reconfigure postfix

This will bring up the configuration window again [where you left off]. Use the up/down arrow keys on your keyboard to select an option [where more than one option is displayed], and the left/right arrow key to choose [ok] so the next window option follows on etc. till all fields are completed by you

  • @iamdom....i did do that but again message appears message '2'(screenshot 2) appears on the screen – avinash Dec 14 '11 at 7:25
