BDR install broken on Ubuntu 14.04

Hi,

I'm installing BDR on a ubuntu 14.04 (Trusty) machine. I can reproduce
this error.
It happens locally with a new VM and on Digital ocean.
The error is:

/var/lib/dpkg/info/postgresql-bdr-9.4.postinst: 95:
/var/lib/dpkg/info/postgresql-bdr-9.4.postinst: db_stop: not found

How can I fix this?

The full installation log is included below.

Regards,

Roland van Laar
