Install add-apt-repository on Debian 9 / Ubuntu 18.04/16.04

[RhetoricalJudo]

If you have a minimal installation of Debian 9 / Ubuntu 18.04 / Ubuntu 16.04, chances are you may not have commandadd-apt-repository present in your system. If you get the error “add-apt-repository command not found” while trying to add PPA repository, you’ll need to install add-apt-repository

For those new to Debian package management, add-apt-repository is a command line tool used for adding Personal Package Archive (PPA ) in Debian family Linux distributions.

If your system is missing add-apt-repository command, install the software-properties-common package by running the following command in your terminal:

 
 sudo apt update sudo apt -y install software-properties-common dirmngr apt-transport-https lsb-release ca-certificates

You can now add PPA repository with the syntax:

 
 sudo add-apt-repository ppa:<PPA Name>

The example below add PHP PPA repository

 
 sudo add-apt-repository ppa:ondrej/php

Once the PPA repository is added, update the package list and install your new package from the repository.

 
 sudo apt update sudo apt install <package>
