How to Install Linux Mainline Kernel on Ubuntu 22.04 LTS

Ubuntu users, especially LTS users, are well aware that the current shipped kernel focuses on stability over bleeding-edge Linux mainline kernel releases. This is an excellent method for those seeking a stable, uninterrupted environment, but you may often have new hardware that requires a more recent kernel with support for it. An excellent option for Ubuntu desktop users to solve this is the Ubuntu Mainline Kernel Installer, which features a graphical UI that provides the option to install the latest kernel and other versions if you are after a particular version.

Currently, other options exist to upgrade to different kernels or the latest. For Ubuntu desktop users, the Ubuntu Mainline Kernel installer is perhaps one of the most straightforward options users, especially those newer to Linux and Ubuntu and not confident yet in using the command line terminal and prefer a desktop graphical UI.
