ERPNext installation - Cannot start Nginx

Hi, first of all thanks a lot for ERPNext. I am not that skilled in Linux and google most of the stuff we need. I am having a problem that I cant figure out. Following the Hitchiker’s Guide

At the last step I get this error setting up Nginx, with this command
sudo service nginx restart I get this error.

Job for nginx.service failed because the control process exited with error code.
See “systemctl status nginx.service” and “journalctl -xe” for details.

sudo systemctl status nginx.service

Any idea what I am doing wrong ?

If you’re not that skilled then you’re better off using the easy install method found here.

Thanks will try this way.
