Hi, I have the same issue. It was working fine a month ago. I wrote a cookbook with chef to install BDR a month ago since then I did not change the cookbook but now I got this error.
This seem to be the heart of the issue: Removing obsolete dictionary files: ==> ldev4: * No PostgreSQL clusters exist; see "man pg_createcluster" ==> ldev4: /usr/share/postgresql-common/maintscripts-functions: line 95: db_stop: command not found ==> ldev4: dpkg: error processing package postgresql-bdr-9.4 (--configure): ==> ldev4: subprocess installed post-installation script returned error exit status 127 Anyone know what's going on ? I'm going to investigate. Thanks for your replies, Rémy
