In Linux, you've already learned how to update and upgrade software on your machines. When using the apt update and apt upgrade command, they might already install security updates for you. But when you run apt upgrade, it doesn't upgrade the core operating system. In Windows, our OS package is Windows 10, in Linux, it's the kernel along with other packages. The kernel controls the core components of our operating system. Like our word processors, the kernel is just another package. The kernel developers regularly include security patches, new features and fixes for bugs in their updates. If you want to to get all these things, you should be running a new kernel. To first view what kernel version you have, we're going to learn a new command called uname, the uname command gives us the system information. If you use the -r flag for kernel release you'll see what kernel version you have. You can see that I have kernel version 4.1 on here. To update the kernel and other packages, we use our nifty app command with the option full dash upgrade. Before running this command, remember to update your application sources with apt update, sudo apt update And now we can run sudo apt full upgrade. If there's a new version of the kernel available, it'll install it for us. Once you reboot the computer you can start using it. You can verify the latest kernel is being used with the uname -r command. We left out a few details about kernal installations and security updates. But this is a good start to updating your system. With that, we've covered all the essentials to help you hit the ground running with software installation and maintenance. Great work. You learned how to install stand alone packages, use package managers and work with archives, device drivers and core operating system updates. These skills will be super useful as an IT support specialist.
