Title:
  Crash installing packages using debconf

Status in packagekit package in Ubuntu:
  Fix Released
Status in packagekit source package in Bionic:
  Fix Released

Bug description:
  [Impact]
  Installing .deb package via PackageKit (e.g. using GNOME Software) don't work reliably when the packages use debconf. This is due to a faulty implementation of debconf handling in PackageKit.

  [Test Case]
  1. Download opera deb file from opera.com
  2. Run the file to launch gnome-software
  3. Install it
  4. Proceed with the debconf prompt

  Expected result:
  A debconf dialog appears asking if you want to "update Opera with the rest of the system?". The dialog closes when completed and the package is installed.

  Actual result:
  The dialog shows, but never closes and becomes unresponsive. Force closing the dialog causes a crash.

  [Regression Potential]
  The change is quite large, so there is a reasonable chance of introducing new bugs in debconf handling. However, the existing code has some obviously wrong codepaths, so the new code is probably a lower risk than the existing code.
