GNU/Linux Debian Bullseye Building Kernel 5.17 from Source Code Guide
Hi! This tutorial will guide you step-by-step on How to Build and Install a New Custom Kernel 5.17 from Source Code in Debian Bullseye 11.x GNU/Linux.
Especially relevant: this Debian Bullseye Kernel 5.17 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.
Finally, for a Non Bootable System before see: How to chroot on Debian GNU/Linux Tutorial.

If Got “User is Not in Sudoers file” then see: How to Enable sudo.How to QuickStart with Command Line on Debian GNU/Linux
2. Making Target Directory
Now make the Target Folder
With:mkdir ~/kernel
3. Downloading Linux Kernel

Then Extract Linux Kernel into the target Directory
First, access it:cd ~/kernel
Then to untar the downloaded Kernel Source into the current Folder run:tar -xavf ~/Downloads/linux*.tar.xz
