How To Install Kernel Headers on Ubuntu

Install Kernel Headers on Ubuntu

In this tutorial, we will show you how to install Kernel Headers on Ubuntu. For those of you who didn’t know, Kernel headers are files that provide the necessary information for building kernel modules, which are programs that can be loaded into the kernel at runtime to extend its functionality. These headers contain information about the internal data structures and function calls used by the kernel, and they are required for building out-of-tree kernel modules, which are modules that are not included in the official kernel source code.

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 the Kernel Headers on Ubuntu Linux. You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.


  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, 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. You’ll need an internet connection to download the necessary packages and dependencies for Kernel Headers.
  • 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.
