 Upgrading your Linux kernel to a the highest version can help boost performance in some use cases however if a novice does it they can lose internet connectivity or get a black screen for doing it wrong this guide is aimed at intermediate to advanced who are power users who won't break their systems like a novice user. Anyway  onward. I will now show you a list of commands and I want you to understand the risks on doing it wrong will do. However if you do it correctly you will enjoy benefits like better driver support, better performance and security from upgrading to the highest kernel you can upgrade to. Shall I begin now I gave you this disclaimer warning.  The following will be how to install manually the kernel dependencies with dpkg  you will have to install 4 .deb packages the2 headers packages the linux-image package and the linux-modules package with "sudo dpkg -i thepackage.deb" you can also use --force-all to force install them like this "sudo dpkg -i --f...
