Further I am trying to install devstack, but some network error after executing the following:

$ git clone https://git.openstack.org/openstack-dev/devstack
Cloning into 'devstack'...
fatal: unable to access 'https://git.openstack.org/openstack-dev/devstack/': Failed to connect to git.openstack.org port 443: Network is unreachable
  • you already have git installed. What are you trying to do ? Get git before devstack? What's your ubuntu version?

I followed this link

and was able to install it without any issues. I am having Ubuntu Desktop 14.04.3 LTS
