Adding Extra apt-get Lists

With Ubuntu, there are many different ways to add additional apt-get lists, either directly by sudo nano ..., sudo add-apt-repository ppa:nginx/main, etc.

Release-Specific Lists

When adding an apt-get list to your system, one nice way to save your code in your notes or to automate through scripting is not by specific system names, like Ubuntu’s xenial, and Debian’s Jessie release names; but rather to insert code into your echo so that it works for you!

echo "deb $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/cisofy-linus.list


  1. Most all apt-get .list lines begin with deb or deb-src
  2. Then, the html address of the library
  3. Next, usually the name of the release you are using, such as xenial for 16.04 Ubuntu or jessie for Debian 8.
  4. And last, there are names for the various extra sections you can discern between - main, extras or whatever else the library maintainer uses.


The key text is $(lsb_release -sc). When you input $( ) it tells bash to execute the command inside the parenthesis, and use the output inside the echo text.


or more of Ubuntu’s Shenanigans

Ubuntu seems to have a small habit of taking industry- and community-standardized processes and libraries and applications and putting - or sometimes shoving - their own special twist on things.

Take Ubuntu’s PPA system. As a developer on Ubuntu’s Launchpad website, you get your own PPA address, apt repository, and a central means of distributing your code to Ubuntu Users.

Its super simple to add these repo’s to Ubuntu:

sudo add-apt-repository ppa:nginx/main
sudo apt-get update && sudo apt-get install $application

You’ll want to always run apt-get update to pull the lists of available programs to install, and then install the additional program or to upgrade existing programs already installed

Personal Standards

When I add apt-get lists that are seperate from the standard or even non-standard Ubuntu Lists and Libraries, such as NGINX’s lists, nodesource lists for Node and NPM, etc., I have them in seperate, short lists.

The directory tree breakdown is as follows:

├── mono-xamarin.list
├── nginx-amplify.list
├── nginx-ubuntu-development-xenial.list
├── nodesource.list
└── ondrej-ubuntu-php-xenial.list

This way, removing specific items is MUCH easier.
