Section: Debconf (8)
dpkg-reconfigure [options] packages
dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a package or packages to reconfigure. It will ask configuration questions, much like when the package was first installed.
Note that if you normally have debconf set to use the noninteractive frontend, dpkg-reconfigure will use the dialog frontend instead, so you actually get to reconfigure the package.
