Title:
  DPKG_MAINTSCRIPT_PACKAGE not set by dpkg-reconfigure causing dpkg-
  trigger to fail

Status in “debconf” package in Ubuntu:
  In Progress
Status in “debconf” package in Debian:
  Fix Released

Bug description:
  Binary package hint: debconf

  When reconfiguring a package that uses dpkg-trigger it fails with:

  dpkg-trigger: dpkg-trigger must be called from a maintainer script (or
  with a --by-package option)

  For instance:

  $ sudo dpkg-reconfigure selinux
  dpkg-trigger: dpkg-trigger must be called from a maintainer script (or with a --by-package option)

  Setting DPKG_MAINTSCRIPT_PACKAGE fixes the problem:

  $ sudo DPKG_MAINTSCRIPT_PACKAGE=selinux dpkg-reconfigure selinux

  The usage of dpkg-trigger indicates that this is normally setup by dpkg:
  $dpkg-trigger --help
  ...
    --by-package=<package>   Override trigger awaiter (normally set by dpkg).
  ...
