GNU/Linux Debian Bullseye Building Kernel 6.5 from Source Code Guide

Hi! The Tutorial Shows You Step-by-step How to Build and Install a New Custom Kernel 6.5 from Source Code in Debian Bullseye 11.x GNU/Linux.

Especially relevant: this Debian Bullseye Kernel 6.5 Setup make use of the latest Source Code.

Again this tutorial make it the Easy Way and so is intended especially for Beginners.

Possibly, a very good Alternative for Desktops is represented by the ready-made XanMod and Liquorix Kernel Setup.

Important to know how this Setup does Not change your existing System and so in any case you will be able to startup with the current Kernel from the GRUB Splash Screen.

For further advanced Kernel Configuration instructions you may see the Linux Kernel Documentation.

But for a Non Bootable System before see: How to chroot on Debian GNU/Linux Tutorial.

Finally, this Setup is valid for all the Debian-based Distros like:

• Kali
• MX Linux
• Deepin
• Parrot
• antiX
• SparkyLinux
• Q4OS
• Netrunner
• Voyager Debian
• MakuluLinux
• Elive
• LMDE
• Parsix
(You may just need to Discover what’s the Parent Release)
