How to install the latest Nginx 1.8.0 Stable on Ubuntu Raspberry Pi 2

I installed Ubuntu 15.04 on my Raspberry Pi 2 Model B using this image built by mrengles. I personally prefer Ubuntu over the default Raspbian Wheezy simply because their packages are more stable and up-to-date. However still, the repo has an older version of Nginx (1.6.2). To install the newest Nginx 1.8.0 stable, you will either have to build it from source or install a binary prebuilt by someone. After some googling, I found it here.

Add the ppa repository:

sudo add-apt-repository ppa:teward/nginx-stable-testing

You will see this message:

Staging PPA for nginx/stable PPA.

This contains all builds for the Stable PPA.  Good builds, bad builds, and old builds.  Please do not use this PPA unless you really know what you're doing.

Follow the instruction and press [ENTER].

Go ahead and perform the normal apt-get update and apt-get install:

sudo apt-get update
sudo apt-get install nginx

You may edit the settings from /etc/nginx/nginx.conf and /etc/nginx/sites-available/default as required. Then start Nginx normally:

sudo service nginx start

Open your browser to see if that works.
