dpkg-preconfigure
DPKG-PRECONFIGURE(8) Debconf DPKG-PRECONFIGURE(8)
NAME
dpkg-preconfigure - let packages ask questions prior to their installation
SYNOPSIS
dpkg-preconfigure [options] package.deb
dpkg-preconfigure --apt
DESCRIPTION
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.
OPTIONS
-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.
