Are you a Ubuntu user looking to add new software packages to your system? Adding a repository in Ubuntu can help you install software that is not available in the Ubuntu software center or get more up-to-date packages. In this article, we will guide you through the process of adding a repository in Ubuntu.
What is a Repository in Ubuntu?
A repository in Ubuntu is a collection of software packages hosted in a specific location. The official Ubuntu repositories contain thousands of software packages that are thoroughly tested and maintained by the Ubuntu community. However, third-party repositories also exist, containing software packages not included in the official Ubuntu repositories.
Why Add a Repository in Ubuntu?
Adding a repository in Ubuntu can provide you with access to additional software packages that are not included in the default Ubuntu installation. These packages may include software that is not available in the Ubuntu software center or packages that are more up-to-date than the ones available in the default repositories. Adding a repository can also help you to install software that is specific to your needs, such as development tools or specialized software for scientific research.

Adding a repository in Ubuntu is a simple process that can be done using the command line or the graphical user interface. In this section, we will guide you through the process of adding a repository using both methods.
Using the Command Line
Step 1: Open the Terminal
To add a repository using the command line, the first step is to open the terminal. You can do this by pressing the Ctrl+Alt+T
keys on your keyboard or by searching for “Terminal” in the Ubuntu dash.
Step 2: Add the Repository
To add a repository using the command line, you need to use the add-apt-repository
command. This command will add the repository’s GPG key to your system and update the package lists. For example, to add the repository for the latest version of the popular text editor, Sublime Text
, enter the following command in the terminal:
sudo add-apt-repository -y ppa:webupd8team/sublime-text-3
Step 3: Update the Package Lists
After adding the repository, you need to update the package lists to include the new software packages. To do this, enter the following command in the terminal:
sudo apt update
Step 4: Install the Software
Finally, you can install the software from the newly added repository using the apt install
command. For example, to install Sublime Text
, enter the following command in the terminal:
sudo apt install sublime-text-installer
Using the Graphical User Interface
Step 1: Open the Software & Updates Application
To add a repository using the graphical user interface, open the Software & Updates application. You can do this by searching for “Software & Updates” in the Ubuntu dash.
Step 2: Navigate to the “Other Software” Tab
In the Software & Updates application, navigate to the “Other Software” tab. This tab contains a list of repositories that are not included in the default Ubuntu installation.
Step 3: Add the Repository
To add a new repository, click the “Add” button at the bottom of the window. This will open a new window where you can enter the details of the repository.
In the new window, enter the repository’s URL in the “APT line” field. For example, to add the repository for Sublime Text
, enter the following URL:
deb http://ppa.launchpad.net/webupd8team/sublime-text-3/ubuntu bionic main
You can also add the repository’s GPG key by clicking the “Authentication” button and entering the key details.
Step 4: Update the Package Lists
After adding the repository, you need to update the package lists to include the new software packages. To do this, click the “Reload” button in the Software & Updates application. This will download the latest package lists from all the repositories on your system, including the newly added repository.
Step 5: Install the Software
Finally, you can install the software from the newly added repository using the Ubuntu Software center or the apt install
command.
