Install Linux Kernel 5.15 on Ubuntu 20.04

In this tutorial, we will show you how to install Linux Kernel 5.15 on Ubuntu 20.04 LTS. For those of you who didn’t know, Linux kernel 5.15 was released on October 31st, 2021, and it brings some interesting new features, such as a new NTFS file system implementation that doesn’t require you to rely on third-party software like NTFS-3G to fully manage your NTFS formatted external disk drives.

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 Linux Kernel 5.15 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.
