Install PostgreSQL BDR

For those who get the error:

apt-get install postgresql-bdr-9.4
...
The following packages have unmet dependencies:
postgresql-bdr-9.4: Depends: postgresql-bdr-client-9.4 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

-

apt-get install postgresql-bdr-client-9.4
...
The following packages have unmet dependencies:
postgresql-bdr-client-9.4: Depends: libpq5 (>= 9.4.4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

 

That's my solution based on https://wiki.postgresql.org/wiki/Apt and http://packages.2ndquadrant.com/bdr/apt/

 

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

sudo sh -c 'echo "deb http://packages.2ndquadrant.com/bdr/apt/ $(lsb_release -cs)-2ndquadrant main" > /etc/apt/sources.list.d/2ndquadrant.list.list'

sudo apt-get install wget ca-certificates

sudo wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -

sudo wget --quiet -O - http://packages.2ndquadrant.com/bdr/apt/AA7A6805.asc | sudo apt-key add -

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install postgresql-bdr-9.4 postgresql-bdr-9.4-bdr-plugin
