I am trying to set up the new CloudLaunch app, and I have a few questions related to it:

  1. Is there a way to know when a new version of the CloudLaunch app will be released? E.g. an email list i can sign up for or some schedule posted somewhere? I saw that the old CloudLaunch instructions are gone, replaced with a new version. This rendered my own "enhanced" instructions (which installed additional prerequisites) obsolete. I would like to avoid this for future releases of the app.

  2. What Cloud/OS/version do the new CloudLaunch instructions work with? I have tried to install on AWS Ubuntu 14.04 and Ubuntu 16.04, and in both cases i have to install additional prerequisite software, and i still get errors that I am struggling to overcome. I get furthest with 16.04.

  3. Below is the latest stack trace I encounter on Ubuntu 16.04 when i run python migrate or python runserver. I have not been able to figure out how to fix it. Any thoughts?

    $ python migrate
    Traceback (most recent call last):
      File "/home/ubuntu/launcher/venv/lib/python3.5/site-packages/django/db/backends/base/", line 199, in ensure_connection
      File "/home/ubuntu/launcher/venv/lib/python3.5/site-packages/django/db/backends/base/", line 171, in connect
        self.connection = self.get_new_connection(conn_params)
      File "/home/ubuntu/launcher/venv/lib/python3.5/site-packages/django/db/backends/postgresql/", line 175, in get_new_connection
        connection = Database.connect(**conn_params)
      File "/home/ubuntu/launcher/venv/lib/python3.5/site-packages/psycopg2/", line 130, in connect
        conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
    psycopg2.OperationalError: could not connect to server: Connection refused
            Is the server running on host "localhost" ( and accepting
            TCP/IP connections on port 5432?

I just realized part of my confusion above: when i go to the cloudlaunch github page i am landing in the dev branch, which is marked as the default branch. I do not see a master branch in the list of branches; is this right? The instructions in the BioCloudCentral branch look like the instructions i was working with previously; perhaps that branch was previously the default branch? In any case, the instructions in the dev branch do not produce a functional CloudLaunch app as they currently stand, so it seems odd for that to be the default branch. Perhaps the dev branch instructions replace some part of the BioCloudCentral instructions? Any guidance would be appreciated.
