dpkg-reconfigure - reconfigure an already installed package

       Joey Hess <joeyh@debian.org>

dpkg-reconfigure reconfigures packages after they have already been installed. Pass it the names of a
       package or packages to reconfigure.

       This has the same effect as re-installing the package, basically. I hope one day this will be called by
       dpkg --reconfigure

       This manpage was "borrowed" from debconf.

       dpkg-reconfigure - reconfigure an already installed package

-ftype, --frontend=type
           Select the frontend to use. The default frontend can be permanently changed by:

            dpkg-reconfigure cdebconf

           Note that if you normally have cdebconf set to use the noninteractive frontend, dpkg-reconfigure will
           use the dialog frontend instead, so you actually get to reconfigure the package.

       -pvalue, --priority=value
           Specify the minimum priority of question that will be displayed.  dpkg-reconfigure normally shows low
           priority questions no matter what your default priority is.

       --all
           Reconfigure all installed packages that use cdebconf. Warning: this may take a long time.

       -u, --unseen-only
           By  default,  all  questions are shown, even if they have already been answered. If this parameter is
           set though, only questions that have not yet been seen will be asked.

       --force
           Force dpkg-reconfigure to reconfigure a package even if the package is in an inconsistent  or  broken
           state. Use with caution.

       -h, --help
           Display usage help.
