In this guide, you will learn two methods to know the kernel version of your Ubuntu Linux computer. To be precise, I will teach you how to execute this task using the uname command.
This guide will also offer procedures to get the kernel version in Ubuntu Linux using the hostnamectl command.
Aside from that, I will include an FAQ section in this guide. As expected, that section will feature answers to a few of the most asked questions relating to this guide’s topic.
Before we proceed, you should know that the procedures in this guide are demonstrated using the Ubuntu 22.04 LTS operating system. Hence, expect the procedures to be slightly different if you use other versions of the Ubuntu Linux-based operating system.
Display Kernel Version in Linux Using Uname Command
One of the most popular commands to get the kernel version of your Ubuntu Linux-based computer is the uname command. This command is a Linux command for getting various system information, including the kernel version.
So, follow the steps below to learn how to use this command to check the kernel version of your Ubuntu PC.
- Open the Ubuntu terminal by right-clicking any free space on the desktop and selecting Open in Terminal from the context menu. Alternatively, you can open the Ubuntu terminal using the Ctrl + Alt + T keyboard shortcut.
- When the terminal opens, input the command below and press the enter key on your computer’s keyboard.
- Consequently, the kernel version of your Ubuntu Linux-based computer should display.
Show Kernal Version in Linux with Hostnamectl Command
Another command you can use to know the kernel version of your Ubuntu Linux-based computer is the hostnamectl command. Although this command is mostly used to check and change the computer name, it also displays the kernel version.
Hence, the following procedures will demonstrate how to use the command to display the kernal version of your Ubutu Linux PC.
- On the Ubuntu desktop, right-click any free area and left-click Open in Terminal from the context menu that appears. Alternatively, use the Ctrl + Alt + T keyboard shortcut to open the Ubuntu terminal.
- In the Ubuntu terminal, execute the command below. Hence, you will see the kernel version of your computer among the command’s output – see the second screenshot.
Frequently Asked Questions
A kernel is a computer program that sits at the heart of a computer’s operating system and has complete control over everything in the computer. It is a section of the operating system code that is always in the memory and facilitates interactions between hardware and software components.
Moreover, on most computers, the kernel is one of the first programs to be loaded on startup, right after the bootloader. Hence, it handles the rest of the startup.
Also, it manages memory, peripherals, and input/output (I/O) requests from software. Thereby translating them into data-processing instructions for the CPU.
Yes, every operating system available has a kernel.
To display the kernel version of your Ubuntu PC, follow the steps below.
a) Press the Ctrl + Alt + T keys on your keyboard simultaneously to open the Ubuntu terminal.
b) When the terminal opens, input “uname -r” and press the enter key.
c) Hence, you should see the kernel version of your Ubuntu Linux-based computer.

Yes, the Ubuntu operating system is one of the many distributions of the Linux operating system.
My Final Thoughts
In the world of operating systems, the kernel is a crucial component that handles essential tasks like managing system resources and facilitating communication between software and hardware. Thus, knowing the kernel version of the operating system running on your computer can be important for troubleshooting, software compatibility, and security updates.
Gladly, this guide demonstrated multiple methods to check the kernel version of your Ubuntu Linux-based computer. To be specific, we learned how to perform this task using the uname command.
That’s not all; this guide also provided steps to get the kernel version in Ubuntu Linux using the hostnamectl command.
