PPA is a way for individual developers or teams to host and distribute their software packages on the Ubuntu platform.

In Linux systems, software packages are typically distributed and installed using package managers and package management systems.

These systems use a central software repository,  which is a collection of software packages that can be easily downloaded and installed on a user’s system.

The package manager uses information from the repository to determine which packages are available, what versions of those packages are available, and what dependencies need to be satisfied in order to install a particular package.

Popular package management systems used in Linux include apt (used by Debian and Ubuntu), yum (used by Red Hat and CentOS), and Pacman (used by Arch Linux).

The package manager typically provides commands for searching, installing, updating, and removing packages from the system.

However, these package managers also have some limitations, like slow release cycles and package conflicts. These limitations can be overcome by utilizing PPA.

Let’s see what exactly this PPA is all about.

What is PPA?


PPA stands for Personal Package Archive, which is a software repository for Debian-based Linux distributions (such as Ubuntu) that allows individual developers and teams to publish their own packages and make them available to other users.

With PPA, the developers can easily package, distribute, and manage their software, and the users can easily install, update, and remove software packages.

PPAs provide a way for developers to distribute software that is not included in the official repositories of a Linux distribution or to provide newer versions of software than what is available in the official repositories.

In order to use PPA, users need to add the PPA repository to their system and then use their package manager to install packages from the PPA.

PPAs are maintained by the developers and are not subject to the same level of examination as packages in the official repositories. So users should be cautious when installing packages from a PPA and should ensure that the PPA is trusted and reliable.

How PPA works?

Here’s a brief overview of how PPA works.

#1. Package Creation

A developer creates a software package that includes the necessary files, dependencies, and installation scripts. The package is built using the Debian packaging system, which allows it to be easily installed and managed on Debian-based systems.

#2. PPA Creation

The developer creates a PPA on the Launchpad platform, which is a web-based service provided by Canonical (publisher of ubuntu) that provides a way to host, manage, and distribute software packages.

#3. Package Upload

The developer uploads the package to their PPA along with information about the package, such as its dependencies, version number, and description.

#4. Package Building

Launchpad automatically builds the package for each supported distribution and architecture. This process ensures that the package is compatible with the target system and is ready to be installed.

#5. Package Distribution

Once the package has been built, it is available for users to download and install from the PPA.

#6. Package Management

Users can add the PPA repository to their system and then use their package manager to install, update, or remove packages from the PPA.

PPA provides a convenient way for developers to distribute their software and for users to manage their software installations. By leveraging the capabilities of the Launchpad platform and the Debian packaging system, PPA makes it easy to manage software installations and ensures that users have access to the latest and most relevant packages.

Official PPA vs. Unofficial PPA

The main difference between official and unofficial PPAs is the source of the packages they contain.

Official PPA – These PPAs are managed and maintained by Canonical (the company behind Ubuntu) or other trusted organizations. They contain software that is officially endorsed by Ubuntu and are usually considered safe to use.

Unofficial PPA – These are created and maintained by individuals or organizations not affiliated with Ubuntu. They may contain software not officially endorsed by Ubuntu, and the quality & security of the software they contain can vary.

How to add PPA on Ubuntu?

To add a PPA on Ubuntu, Simply follow these steps:

Open a terminal. You can do this by pressing the Ctrl + Alt + T keyboard shortcut.

To add PPA to the ubuntu system, first, you need to install this software-properties-common package using the below command.

sudo apt-get install software-properties-common

Then Add the PPA repository – Use the following command to add a PPA to your system, replace ppa:user/repo with the actual PPA repository, you want to add.

sudo add-apt-repository ppa:user/repo

Here, I want to add notepadqq PPA.


You could encounter the add-apt-repository command missing problem on Debian and occasionally on Ubuntu. That error may look like this.

sudo: add-apt-repository: command not found

It’s because the add-apt-repository command is part of the package software-properties-common, and you need to re-install this package in order to install the add-apt-repository.

Update the package list – After adding the PPA repository, update the package list by running the following command.

sudo apt update

Install packages – Finally, you can install packages from the newly added PPA repository using the following command by replacing “package-name” with the actual package name you want to install.

sudo apt install package-name

Note: Before adding a PPA, it’s always a good idea to check its reliability and safety from its source. Some PPAs may contain malware or outdated software, so it’s important to be cautious when adding PPAs to your system.

How to Remove PPA on Ubuntu?

You can easily remove PPA on ubuntu by following the below steps.

And the first step is to list all the installed PPAs on your system. For that, run the following command on the terminal.

ls /etc/apt/sources.list.d/

Remove PPA repository – To delete a specific PPA repository from the system, use the following command by replacing ppa: user/repo with the actual PPA repository, you want to remove.

sudo add-apt-repository --remove ppa:user/repo

Here, I have chosen to remove the PPA installed above.


Removing a PPA will also remove any packages installed from that PPA. If you want to keep the packages installed from that PPA, then consider using a different method, such as pinning, to prevent them from being updated.

Advantages of PPA

Here are some advantages of using Personal Package Archives (PPAs) on Ubuntu.

Easy software distribution

PPAs provide a simple way for developers to distribute their software to a larger audience, making it easier for users to install and receive updates for that software.

Regular updates

They can be updated regularly, which provides users with the latest versions of the software they have installed from the PPA.

Test new software

PPAs provide a way for users to test new software that is not yet included in the official repositories without affecting the stability of their system.

No need for a compilation

They allow users to install pre-compiled packages, making it easier and faster to install software than compiling it from source code. This is particularly useful for users who are not experienced with compiling software from source code.

Custom repositories

These can also be used to create custom repositories for specific groups of users, allowing them to easily access and install packages that are not included in the official repositories.

Security Issues with PPA

PPAs can introduce security risks to your Ubuntu system as they may contain malware, outdated software, or packages with known vulnerabilities. Here are a few security issues with PPAs:

Unverified sources

PPAs can be created by anyone and may not be thoroughly examined for security and quality.

Outdated software

They may not be updated regularly and may contain outdated software with known vulnerabilities.

Malicious software

These PPAs contain malicious software, such as malware or spyware, that could compromise the security of your system.

Package conflict

They can cause package conflicts with other packages installed on your system, which leads to unexpected behavior or system instability.
