package apport 1.20.1-0ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Binary package hint: apport

This has crashed on both my laptops. Seems both apport 1.20.1-0ubuntu4 and 3 along with apport-gtk 1.20.1-0ubuntu4 and 3 fail on install. The error message report apport-gtk depends on apport (>= 0.41); however Package apport is not configured yet.
