How To Add Mainline Kernel PPA to Synaptic

Ubuntu 21

In this article, we will walk you through the process of adding the Mainline Kernel PPA to Synaptic. This is a crucial step for those who wish to stay updated with the latest kernel releases. We will cover two methods: using the Terminal and using the Synaptic Package Manager.

Quick Answer

To add the Mainline Kernel PPA to Synaptic, you can use either the Terminal or the Synaptic Package Manager. In the Terminal, use the command "sudo add-apt-repository ppa:cappelikan/ppa" to add the PPA, and then update the software sources with "sudo apt update". In Synaptic, go to "Settings" > "Repositories" > "Other Software" and add the PPA URL, then update the package information.

What is a PPA?

PPA stands for Personal Package Archive. It’s a repository of software that isn’t included in the official Ubuntu repositories. PPAs can be created by any user and can contain any software. In this case, we’re interested in the Mainline Kernel PPA, which contains the latest releases of the Linux kernel.

Method 1: Using the Terminal

The Terminal is a powerful tool that allows you to control your system with text-based commands. Here’s how to add the Mainline Kernel PPA using the Terminal:

Step 1: Open the Terminal

You can open a terminal by pressing Ctrl+Alt+T.

Step 2: Add the PPA

To add the PPA, run the following command:

sudo add-apt-repository ppa:cappelikan/ppa

In this command, sudo is used to run the command as the root user, which is necessary because adding a PPA is a system-wide change. add-apt-repository is the command to add a new repository, and ppa:cappelikan/ppa is the PPA we’re adding.

You’ll be asked for your password. Enter it and press Enter.

Step 3: Update the Software Sources

After adding the PPA, you need to update your system’s software sources with the following command:

sudo apt update

Again, sudo is used to run the command as the root user. apt is the package handling utility in Ubuntu, and update is the command to update the list of available packages.

Method 2: Using the Synaptic Package Manager

The Synaptic Package Manager is a graphical interface for managing your software. Here’s how to add the Mainline Kernel PPA using Synaptic:

Step 1: Open the Synaptic Package Manager

You can open the Synaptic Package Manager by searching for “Synaptic” in the application launcher.

Step 2: Add the PPA

In the Synaptic Package Manager, click on the “Settings” menu and select “Repositories”. In the “Software & Updates” window that opens, go to the “Other Software” tab.

Click on the “Add” button. In the “APT line” field, enter the following line:

deb http://ppa.launchpad.net/cappelikan/ppa/ubuntu focal main

In this line, deb indicates that this is a binary repository (as opposed to a source code repository), http://ppa.launchpad.net/cappelikan/ppa/ubuntu is the URL of the repository, focal is the codename of your Ubuntu version, and main is the component of the repository.

Replace “focal” with your Ubuntu version if you are using a different release.

Click “Add Source” and close the “Software & Updates” window.

Step 3: Update the Package Information

Back in the Synaptic Package Manager, click on the “Reload” button to update the package information.

Conclusion

Whether you prefer using the Terminal or a graphical interface, adding the Mainline Kernel PPA to Synaptic is a straightforward process. By following these steps, you can stay updated with the latest kernel releases. Remember to always be cautious when adding PPAs to your system, as they can potentially contain harmful software. Always add PPAs from trusted sources.
