The debconf source file is missing.
db_stop, stands for debconf stop.

It is supposed to be fixed but it is not.
See this closed issue on Github:
https://github.com/2ndQuadrant/bdr/issues/156

I "fixed" it in ansible by

- installing bdr accepting the fail
- removing the db_stop line
- installing bdr again.

This is the relevant part of my ansible configuration:

- name: install postgresql bdr
   apt:
     name=postgresql-bdr-9.4-bdr-plugin
     state=present
   ignore_errors: yes

- name: remove db_stop from postgres postinstall script
   lineinfile:
     dest=/usr/share/postgresql-common/maintscripts-functions
     regexp=db_stop
     state=absent

- name: reinstall postgresql bdr to mitigate the db_stop problem
   apt:
     name=postgresql-bdr-9.4-bdr-plugin
     state=present
