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 remove.

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

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