I'm going to update nginx to 1.10.3 as per your instructions.
However, I don't use the EasyEngine script. I only use your version of nginx, your recommended settings at nginx.conf and your Nginx helper plugin.
The command for upgrading nginx is:
sudo apt-get -o Dpkg::Options::="--force-confold" install nginx-custom nginx-ee
The command requires "nginx-ee" to be installed, but do I really need "nginx-ee" on my server? Can I remove it and not install it. Will everything work in my case only with "nginx-custom"?
