Additionally, the Liquorix Kernel does not support secure boot, so it must be disabled before installation.

Install Liquorix Kernel on Ubuntu 22.04 or 20.04 via APT PPA

Step 1: Update Ubuntu Before Liquorix Kernel Installation

Before we begin the installation process, ensuring that your system is up to date with the latest packages is essential. To do this, execute the following commands in your terminal:

sudo apt update
sudo apt upgrade

The first command updates the package list, while the second upgrades outdated packages to their latest versions.

Step 2: Import the Liquorix Kernel PPA on Ubuntu

The Liquorix Kernel team offers support through an official Launchpad PPA (Personal Package Archive), making installing and maintaining the kernel easy. Run the following command to import the Liquorix Kernel PPA:

sudo add-apt-repository ppa:damentz/liquorix -y

This command adds the Liquorix repository to your system’s sources.list file.

Next, run a quick update to refresh the APT repository cache, which must be done before the installation:

sudo apt update

Step 3: Install the Liquorix Kernel on Ubuntu 22.04 or 20.04 via APT Command

Now that the Liquorix Kernel PPA is available on your system, you can start the installation process. Use the following command to install the Liquorix kernel:

sudo apt install linux-image-liquorix-amd64

After the installation is complete, reboot your system to activate the newly installed Liquorix kernel:

reboot

Step 4: Verify the Liquorix Kernel Installation on Ubuntu

Once your system has restarted, you can verify that the Liquorix kernel is active by checking the output of the /proc/version file. Use the following command to display its contents:

cat /proc/version

Example output:

Linux version 6.x.x-x-liquorix-amd64

The output should display the Liquorix kernel version, which may vary depending on the current version available in the PPA.

Remove Liqourix Kernel From Ubuntu 22.04 or 20.04

If you have decided not to continue using the Liquorix kernel and wish to remove the PPA, use the following command.

sudo add-apt-repository --remove ppa:damentz/liquorix -y

Note that you must specify the exact name of the Linux image and header package to remove them. You can find the names by running the following command.

dpkg --list | grep `uname -r`

To remove the kernel packages, use the provided command, which should cover all versions of Liquorix. However, modify the command to match the kernel version in your output if necessary.

sudo apt-get autoremove linux-image-*.*.-*.*-liquorix-amd64 linux-headers-*.*.*-*.*-liquorix-amd64 --purge

While removing the Liquorix Kernel, you may encounter a prompt asking for confirmation to proceed with the removal.

During the removal process for the Liquorix Kernel, a warning message may appear about not having a fallback Linux Kernel to rely on during a reboot. Selecting “No” to proceed with the removal process is essential.

Once you have removed the Liquorix kernel, run the following command to ensure the generic Linux Kernel is installed. You can change this later on for users wanting something else.

sudo apt install linux-image-generic

Now restart your PC to finalize the removal of Liquorix.

reboot

To confirm that the Liquorix kernel has been successfully removed, you can check the installed kernel version using a command like “cat /proc/version” and compare the output to the version of the Liquorix kernel you had previously installed.

cat /proc/version

Example output if the default kernel is restored:

Linux version 5.x.x

Conclusion

In conclusion, installing the Liquorix kernel on Ubuntu is a simple process that can significantly improve users’ performance. However, if you are unsatisfied with the results or experience any issues, you may want to consider an alternative kernel such as Xanmod. Ultimately, the choice of the kernel will depend on your individual needs and preferences. It is essential to keep in mind that kernels are constantly updated, so staying up to date with the latest version can ensure optimal performance.
