dpkg-preconfigure

 dpkg-preconfigure [options] package.deb
 dpkg-preconfigure --apt

dpkg-preconfigure lets packages ask questions before they are installed. It operates on a set of debian packages, and all packages that use debconf will have their config script run so they can examine the system and ask questions.

-ftype, --frontend=type

Select the frontend to use.

-pvalue, --priority=value

Set the lowest priority of questions you are interested in. Any questions with a priority below the selected priority will be ignored and their default answers will be used.

--terse

Enables terse output mode. This affects only some frontends.

--apt

Run in apt mode. It will expect to read a set of package filenames from stdin, rather than getting them as parameters. Typically this is used to make apt run dpkg-preconfigure on all packages before they are installed. To do this, add something like this to /etc/apt/apt.conf:

 // Pre-configure all packages before
 // they are installed.
 DPkg::Pre-Install-Pkgs {
        "dpkg-preconfigure --apt --priority=low";
 };
    

-h, --help

Display usage help.
