Heads up: limited package support for non-LTS Ubuntu versions

Before we continue, you should know that the Ubuntu version you selected is a non-LTS (Long Term Support) version. This means that Canonical — the company that created Ubuntu — only supports this particular Ubuntu version for 1 year.

Because of this short support cycle by Canonical, we only provide Passenger package updates for this Ubuntu version for 6 months. That's when the next Ubuntu version comes out.

So when the next Ubuntu version is released, you must upgrade your system to that new Ubuntu version. Otherwise you won't receive Passenger updates in the form of .deb packages from us anymore.

If you don't like having to upgrade your Ubuntu system every 6 months, then you should use an LTS version of Ubuntu. Canonical supports LTS versions for 5 years, and we provide Passenger package updates for LTS versions for 5 years too.

Now that you know this, let's move on.

Step 1: install Passenger packages

These commands will install Passenger through Phusion's APT repository.

# Install our PGP key and add HTTPS support for APT
sudo apt-get install -y dirmngr gnupg
sudo apt-key adv --keyserver hkp:// --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates

# Add our APT repository
sudo sh -c 'echo deb artful main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update

# Install Passenger
sudo apt-get install -y passenger

Step 2: check installation

After installation, please validate the install by running sudo /usr/bin/passenger-config validate-install. For example:

$ sudo /usr/bin/passenger-config validate-install
 * Checking whether this Phusion Passenger install is in PATH... ✓
 * Checking whether there are no other Phusion Passenger installations... ✓

All checks should pass. If any of the checks do not pass, please follow the suggestions on screen.

Step 3: update regularly

Passenger updates and system updates are delivered through the APT package manager regularly. You should run the following command regularly to keep them up to date:

$ sudo apt-get update
$ sudo apt-get upgrade

After an update, you should restart all your Passenger instances so that the updates take effect.

Next step

Now that you have installed Passenger, you are ready to deploy your Python application on the production server!
