#Error sudo apt update install#
As an end-user, you can add the PPA repo to your sources.list file and upon updating your Ubuntu system, your system will then know the availability of the software and allow you to install it using the APT package manager.įor example, to install FFmpeg4, you would add the ffmpeg4 launchpad PPA as follows: $ sudo add-apt-repository ppa:jonathonf/ffmpeg-4
Thankfully, Ubuntu provides Launchpad, which is a platform that allows developers to create their own repositories. Installing software applications using PPAs. Similarly, when a developer wishes their application to be included in Ubuntu’s official repositories, Ubuntu takes time before making the final decision on whether or not to include the application in its official repositories.Īnd this is where PPA comes in. This may take several months for the application to be made available and certainly, not everyone is willing to wait that long to get the application. They carry out multiple tests to check the compatibility and stability of the application. Usually, Ubuntu will not make it available immediately in their repositories. The problem arises when a developer releases their own version of the software. Ubuntu’s APT package manager stores a list of repositories in the /etc/apt/sources.list file.Įssentially, Ubuntu has control over which software packages and versions that you will get on your system.

In fact, Ubuntu has over 47,000 software packages provided by the 4 main repositories. This is a question that you might be asking given that each Ubuntu version comes with its own set of repositories which provide a wide selection of software packages. Why use PPAs instead of relying on Ubuntu’s main repositories? What is it? PPA (Personal Package Archive) is a platform that allows developers to make available their own repositories and distribute their applications.
