debconf is a software utility for performing system-wide configuration tasks on Unix-like operating systems. It is developed for the Debian GNU/Linux distribution, and is closely integrated with Debian’s package management system, dpkg.

When packages are being installed, debconf asks the user questions which determine the contents of the system-wide configuration files associated with that package. After package installation, it is possible to go back and change the configuration of a package by using the dpkg-reconfigure program.

The design of debconf allows for front-ends for answering configuration questions to be added in a modular way, and there exist several, such as one for the terminal, one for KDE, one for GNOME, etc.

If you want to reconfigure your debconf option run the following command

#dpkg-reconfigure debconf

It will open the following screen with frontend options

Debconf Frontend Options

dialog

According to standard the used front-end on basis of whiptail or to dialogue. A simple graphic surface on text basis

This front-end is for *nix Freaks,
