Start with Pre-installation step

and include /usr/sbin in system $PATH variable.
On Debian Trixie stable vs Testing install libdw-dev and build dependencies step is required to succeed with build CachyOS 6.16.5 Kernel on Debian 13
$ sudo apt install libdw-dev
$ sudo apt-get build-dep libdw-dev
Proceed with cloning https://github.com/Nitrux/linux-cachyos-deb
$ git clone https://github.com/Nitrux/linux-cachyos-deb
$ cd linux-cachyos-deb
Script installs all required packages and pops up TUI dialog to configure kernel 6.16.5 and finally proceed with building of debian kernel packages.
$ ./cachy-kernel-deb
Upon build completition
