Postal quick installation fix

install_postal.sh

#!/bin/bash

# This will install everything required to run a basic Postal installation.
# This should be run on a clean Ubuntu 16.04 server.
#
# Once the installation has completed you will be able to access the Postal web
# interface on port 443. It will have a self-signed certificate.
#
# * Change the MySQL & RabbitMQ passwords
# * Create your first admin user with 'postal make-user'
# * Replace the self-signed certificate in /etc/nginx/ssl/postal.cert
# * Make appropriate changes to the configuration in /opt/postal/config/postal.yml
# * Setup your DNS                          [ https://github.com/atech/postal/wiki/Domains-&-DNS-Configuration ]
# * Configure the click & open tracking     [ https://github.com/atech/postal/wiki/Click-&-Open-Tracking ]
# * Configure spam & virus checking         [ https://github.com/atech/postal/wiki/Spam-&-Virus-Checking ]

Hi Naveed,

I tried your command worked fine over Vulltr as well.. but I got a new server over Contabo

& got this,

Fetching gem metadata from https://rubygems.org/............
Fetching https://github.com/mikel/mail.git
Your bundle is locked to mimemagic (0.3.5), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that
means the author of mimemagic (0.3.5) has removed it. You'll need to update your bundle to a version other than mimemagic (0.3.5) that hasn't been removed in order to
install.

& when I tried for the second time it says the same:

Reading package lists... Done
E: The repository 'http://www.rabbitmq.com/debian testing Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
