How to Install Kernel 6.5 from Source on Kali

Installing

5. 5. Configuring Kernel

   So now to Configure Kali Custom Linux Kernel
   First, access the Kernel Source with:

   cd linux*

   Then copy the current Configuration File into the New Kernel Source:

   cp /boot/config*`uname -r` .config

   In case of a Chrooted System instead yuo may look up the available Kernels with:

   ls /boot | grep config

   The grep Command refine the output List showing only the entries Matching the Keyword.
   Again fix the Configuration File editing it with nano and commenting out like:

   sudo nano .config

   Use Ctrl+w to search for “CONFIG_SYSTEM_TRUSTED_KEYS” on nano.
   And comment out the Line like:

   #CONFIG_SYSTEM_TRUSTED_KEYS="debian/certs/debian-uefi-certs.pem"

   Ctrl+x to Save & Exit.
   Else to make a Custom one then reconfigure the Kernel (Only for advanced Users) with:

   sudo make menuconfig

   For instructions see: How to Configure a Build Kernel.

6. 6. Building Kernel

   Next to Build Kali Custom Linux Kernel
   Make it with:

   sudo make clean

   And then:

   sudo make deb-pkg LOCALVERSION=-custom KDEB_PKGVERSION=$(make kernelversion)-1
   

   When prompted if uncertain then simply follow to hit Enter until the end.

   

   Then think to other task to follow because the process will take about a couple of Hours…
   Last, to check the builded Images play:

   ls ../*.deb | grep image

   

7. 7. Installing Kernel

   Finally, to Install Kali Custom Linux Kernel
   Simply play:

   sudo dpkg -i ../linux-image*custom_*.deb ../linux-headers*.deb

   And this setup includes also the Custom Kernel Headers that you don’t will find online…
   And finally reboot with:

   sudo reboot now

   Finally, you should boot into your barely new Kali Linux Kernel :)
   To check it run:

   uname -r

   In case of Issues you still can choose the previous one on the GRUB Splash Screen.
