[Bug 198421] Re: DPKG_MAINTSCRIPT_PACKAGE not set by dpkg-reconfigure causing dpkg-trigger to fail

[Colin Watson]

debconf (1.5.42ubuntu1) precise; urgency=low

  * Resynchronise with Debian.  Remaining changes:
    - Gnome.pm: Do not show "Cancel" or "Close" buttons, to avoid breaking
      maintainer scripts.
  * Ubuntu's dpkg-query still uses ${PackageSpec} for multiarch support
    rather than the newer ${binary:Package}.  Support this as well for now.

  [ Joey Hess ]
  * Add a belt-and-suspenders test that Text::CharWidth::mblen is not
    returning bogus values, before using Text::WrapI18n. See #641957
  * Avoid an uninitialized value warning when a blank line is received
    from the client. Closes: #651642

  [ Colin Watson ]
  * Remove all hardcoded executable paths, using a new Debconf::Path module.

  [ Raphaël Hertzog ]
  * Set environment variables expected by maintainer scripts. Closes:
    #560317
  * Do not hardcode the path of maintainer scripts, in order to support the
    multiarch layout.

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

Status in “debconf” package in Ubuntu:
  Fix Released
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).
  ...

  DISTRIB_ID=Ubuntu
  DISTRIB_RELEASE=8.04
