How to update Linux Kernel to the latest version easily

Linux kernel is like the core of the operating system. It’s a piece of software that works as a middle interface between the hardware and the OS. As with every passing day, some new hardware support is added into the kernel and some existing hardware support is improved. This makes updating to the latest kernel highly beneficial, as you get better hardware support and sometimes also more efficiency.

If you are running a Linux operating system, its always a good idea to update the system to latest kernel. Do you have a older PC lying around here are the best Linux distros to bring a new life to your PC.

Begin the Linux kernel update

Now to upgrade, execute the below command in terminal.

sudo apt-get dist-upgrade

This above “dist-upgrade” asks Ubuntu to handle dependencies smartly. That is if a particular software package is dependent on another package to run, then this command will make sure the the dependent package is installed first then only the other package is updated or installed.
