How to Check Ubuntu Version

Ubuntu is a popular Linux distribution that is used by millions of people around the world. It is a free and open-source operating system that is based on the Debian distribution. Ubuntu is known for its ease of use and its large community of users and developers.

There are several different ways to check the version of Ubuntu that you are running. The most common way is to use the lsb_release command. This command will print out the version of Ubuntu that you are running, as well as other information about your system.

To use the lsb_release command, open a terminal window and type the following command:

lsb_release -a

The output of this command will look something like this:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.5 LTS
Release:        20.04
Codename:       focal

The Distributor ID line tells you the name of the Linux distribution that you are running. In this case, we are running Ubuntu. The Description line tells you the version of Ubuntu that you are running. In this case, we are running Ubuntu 20.04.5 LTS. The Release line tells you the release number of Ubuntu that you are running. In this case, we are running release 20.04. The Codename line tells you the codename of the Ubuntu release that you are running. In this case, we are running the "focal" release.

Another way to check the version of Ubuntu that you are running is to use the uname command. This command will print out the kernel version of your system. The kernel is the core of the operating system, and it is responsible for managing the hardware and software on your computer.

To use the uname command, open a terminal window and type the following command:

uname -r

The output of this command will look something like this:

5.15.0-53-generic

The first part of the output is the kernel version number. In this case, we are running kernel version 5.15.0-53-generic. The second part of the output is the codename of the kernel. In this case, we are running the "generic" kernel.

You can also check the version of Ubuntu that you are running by looking at the /etc/os-release file. This file contains information about your operating system, including the version number.

To view the /etc/os-release file, open a terminal window and type the following command:

cat /etc/os-release
