Ghost team released v1.0.0 recently which includes several changes in the install process.
This version of Ghost officially supports only Ubuntu 16.04 and NGINX webserver only as mentioned on their install guide.
There are other requirements as well that are generally available only on a VPS or Dedicated server and hence Ghost cannot run on a cPanel/Shared hosting server. This is confirmed by the Ghost team as well and they have mentioned the same on their install guide.
Due to the above restrictions we will have to remove Ghost from our scripts list. We have planned to remove Ghost from our scripts list after 15 days i.e. 15th August 2017
You can refer to the following install guide of Ghost which gives the details about the requirements to run Ghost :
