  12. #          <new-version>
  13. #        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
  14. #          <failed-install-package> <version> `removing'

  19. #     Any necessary prompting should almost always be confined to the
  20. #     post-installation script, and should be protected with a conditional
  21. #     so that unnecessary prompting doesn't happen if a package's
  22. #     installation fails and the `postinst' is called with `abort-upgrade',
  23. #     `abort-remove' or `abort-deconfigure'.
