Ukuu (short for Ubuntu Kernel Update Utility) makes updating your Ubuntu kernel much easier to perform. It downloads newer kernels from the internet, and changes your system to let it use them. All you really have to do is choose which kernel you’d like and reboot into it.

The kernel is basically an important piece of software found in every operating system. It acts as a mediator between the software you run every day (e.g. web browsers), and the hardware that it’s running on. Essentially, without a kernel, other programs cannot function since they can’t access your computer’s resources.

{If Something Goes Wrong, Do Not Panic}
If you install a new new Linux kernel on your Ubuntu machine and it does not work properly, a piece of hardware fails, or any other issues arise you can easily boot in to an older kernel from the GRUB screen then, when back up, use Ukuu to remove the mainline kernel.
