  15. #          <failed-install-package> <version> `removing'
  16. #          <conflicting-package> <version>

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