NAME

       deb-postinst - package post-installation maintainer script

SYNOPSIS

       DEBIAN/postinst

DESCRIPTION

       A package can perform several post-installation actions via maintainer scripts, by including an
       executable postinst file in its control archive (i.e. DEBIAN/postinst during package creation).

       The script can be called in the following ways:

       postinst configure old-version
           After the package was installed.

       postinst triggered "trigger-name..."
           After  the  package was triggered.  The list of space-separated trigger-names is passed as the second
           argument.

       old-postinst abort-upgrade new-version
           If prerm fails during upgrade or fails on failed upgrade.

       old-postinst abort-remove
           If prerm fails during removal.

       postinst abort-deconfigure in-favour new-package new-version
              [ removing old-package old-version ]
           If prerm fails during deconfiguration of a package.

       postinst abort-remove in-favour new-package new-version
           If prerm fails during replacement due to conflict.
