How To Install Liquorix Kernel on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Liquorix Kernel on Ubuntu 20.04 LTS. For those of you who didn’t know, Liqourix Kernel is a free, open-source general-purpose Linux Kernel alternative to the stock kernel with Ubuntu 20.04. Liquorix Kernel is popular amongst Linux Gaming, multimedia, and ultra-low latency requirements and often boasts the latest Linux Kernels, having multiple branches to choose from stable, edge, and development.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Liquorix Kernel on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• An active internet connection.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Liquorix Kernel on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install update-manager-core

Step 2. Installing Liquorix Kernel on Ubuntu 20.04.

By default, Liquorix Kernel is not available on the Ubuntu base repository. Now we add the Liquorix Kernel PPA repository to your Ubuntu system:

sudo add-apt-repository ppa:damentz/liquorix

Next, refresh your APT repository and install it:

sudo apt update
sudo apt install linux-image-liquorix-amd64 linux-headers-liquorix-amd64

Wait for the process to complete, you will need to reboot your system for the new kernel to be fully activated:

reboot

After logging back into your system, verify the newly installed kernel by using the below commands:

sudo uname -r

To keep the Linux kernel you installed with Liquorix up to date, you will run the standard apt update and upgrade commands:
