2 Easy Methods to Add Repositories in Ubuntu

To start the configuring of any software package, you must add a repository first for further seamless procedures. Here, in the following section, I will provide 2 methods for repository adding (using CLI and GUI) in Ubuntu.

You can read our Comparative Analysis of Methods to distinguish between these two methods and best pick one for your needs.

Method 01: Using CLI to Add Repositories in Ubuntu

The CLI (Command Line Interface) lets you add a new repository with a few steps.  Now, I will walk you through two different CLI-based approaches with hands-on illustrations.

A. Utilizing the apt-add-repository Command for Adding Repositories

You can add, update, or remove repositories using a very straightforward command named apt-add-repository. Now for addition, follow the below steps.

Steps to Follow >

➊ First, open the Ubuntu terminal.

➋ Then, run the command mentioned below:

sudo apt-add-repository deb https :// /mozillateam/ppa/ubuntu/ jammy main
  • sudo: Grants root privileges.
  • apt-add-repository: Adds a new repository to the system.
  • deb: Points out repository type in Debian-based distro such as Ubuntu.
  • https :// Repository web address.
  • jammy: Codename for Ubuntu 22.04.
  • main: Indicates that the software packages are within the main repository.
the new repository is added using commandIn the above image, you see that I am adding a new repository to the system.

➌ After that, type the below command and hit ENTER for repository index updation.

sudo apt update
  • sudo: Grants root privileges.
  • apt: The package management tool.
  • update: Action updating the system repository index.

➍ Finally, run this command to display the added repository.

apt-add-repository --list
  • apt-add-repository: Adds/deletes a repository.
  • –list: Enlists all the available system repositories.

B. Using the “Source File” for Adding Repositories

The system directory named (/etc/apt/sources.list.d/) is responsible for repository storage. So, you can insert any new repository by simply modifying the sources.list file from the command line located in that directory.

Steps to Follow >

➊ First, press CTRL+ALT+T to open the terminal.

➋ Secondly, type the below command and hit ENTER.

nano /etc/apt/sources.list
  • nano: Adds/deletes a repository.
  • /etc/apt/sources.list: Opens the sources.list file in the nano text editor.

➌ Now, type the repository address you want to add to the repo URL is added in sources.list file to add repository in ubuntu In the image, for example, I have added the repository named deb http://repo.tld/ubuntu distro component.

➍ After that, press CTRL+S to save the file and then press CTRL+X to exit.

➎ Finally, type the following command and hit the ENTER button.

apt-add-repository --list

Method 02:  Using GUI to Add Repository in Ubuntu

You can use the GUI (Graphical User Interface) to add a new repository to the system which only requires a few easy steps.

Steps to Follow >

➊ Go to Software & and updates GUI to show how to add repository in ubuntu➋ Now, redirect to Other Software, click Add, provide the repository URL, and click Add Source.the repository url is added in the apt line segment ➌ At this point, enter the user password for authentication.enter password for authenticating the add repository in ubuntu➍ Click on Reload to update the software cache.pressing reload to update repository list

➎ Finally, go to the Other Software tab to see the changes in the repository list.the repository list displayed via GUI other software tab So, in the above image, you see I have successfully added a new repository using GUI.

Comparative Analysis of Methods

The following table represents the essence of the aforementioned methods as far as the repository insertion in Ubuntu is concerned.

Methods Pros Cons
Method 1
  • Fast and efficient.
  • Direct access to the source file.
  • Can be overwhelming for novice users.
  • Mistakes in writing commands lead to unwanted situations.
Method 2
  • Easy for beginners.
  • Prone to less error.
  • Hindrance to efficiency.
  • Slower process.

The selection of a method depends on several variables, such as a newbie will find GUI-based visual representations (method 2) easier to grasp. Conversely, the more experienced the user; the more predilection for the CLI- based approaches (method 1). Every technique is effective. They are now up to your personal preference.


In this article, I have tried to present you with the addition of Linux repositories by which you have already made your footsteps active in the realm of software repository configuration. Furthermore, I have significantly contributed to your path by providing pragmatic illustrations. Therefore, I hope to leverage your learning to become professional personnel in Linux software package management.
