Moreover, for those planning to install Liquorix Kernel, be aware that it does not support secure boot. To proceed with the installation, secure boot must be disabled in your system’s BIOS settings.

Now, let’s get started with the installation process.

Install Liquorix Kernel on Ubuntu via APT PPA

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The first command updates the package list, while the second upgrades outdated packages to their latest versions.

Import the Liquorix Kernel PPA on Ubuntu

The Liquorix Kernel team offers support through a Liquorix 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

Install the Liquorix Kernel on Ubuntu 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:


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 x.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.

Note: Alternatively, you could install the HWE Kernel to suit your Ubuntu system better for Ubuntu LTS release variants.

Reboot and Verify Restored Ubuntu Default Kernel

Now restart your PC to finalize the removal of Liquorix:


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:
