Sometimes, when adding a new software distribution repository, you will need to use add-apt-repository command, but it fails like this:
sudo: add-apt-repository: command not found
It’s basically saying that add-apt-repository is not installed on the machine. You need to install it. Since, it stays in Python common package, so we need to install that one in order to get add-apt-repository into system.
$ sudo apt-get install software-properties-common python-software-properties
After that, add-apt-repository should be ready to use on your computer.
