I have a working Discourse installation which I have rebuilt multiple times already (Ubuntu Xenial own server).
When I tried to rebuild, I got the message below which is similar to an old one on [Solved]Bootstrap fails, Postgres already running.
For testing, I have rebooted the server multiple times, the old site comes up ok, but rebuild gives an error. I have also removed all plugins/hooks with the exception of docker_manager, so the the configuration is essentially the vanilla app with edited SMTP/Hostname
