DPKG-RECONFIGURE(8)                Debconf                DPKG-RECONFIGURE(8)

NAME
       dpkg-reconfigure - reconfigure an already installed package

SYNOPSIS
        dpkg-reconfigure [options] packages

DESCRIPTION
       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.

       If you just want to see the current configuration of a package, see
       debconf-show(1) instead.

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

            dpkg-reconfigure debconf

           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.

       -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. See debconf(7) for a list.

       --default-priority
           Use whatever the default priority of question is, instead of
           forcing the priority to low.

       -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.

       --no-reload
           Prevent dpkg-reconfigure from reloading templates. Use with
           caution; this will prevent dpkg-reconfigure from repairing broken
           templates databases.  However, it may be useful in constrained
           environments where rewriting the templates database is expensive.

       -h, --help
           Display usage help.
