Reconfiguring an installed package in Ubuntu, Debian, and other Debian based distributions.
It's happened to me several times that I
apt-get install some packages which
prompt me to enter some settings in a
curses interface, but I don't know which
values to enter at the time, or later on realize that I need different settings
than what I had originally entered.
To see the screen that you saw again, just do:
sudo dpkg-reconfigure PKG_NAME
PKG_NAME is the name of the package whose configuration screens
you wish to see again.
