How to check which Ubuntu version you are using

You can easily find out which Ubuntu version you are using by executing a command or by the graphical interface route. Knowing the exact version of the operating system you are using is really important.

As new Ubuntu releases come out every six month while a LTS(Long Term Support) release occurs every two years. This info really helps while seeking help on online forums or while checking a version specific tutorial.

So here I will show you how you can easily check your Ubuntu version using command line as well as using the Graphical method.

How To Check Ubuntu Version Using Command Line

So I have choose to show Command line first as it only requires a single command to find Ubuntu version. And this method is also very standard and should also work on most of other Linux Operating systems.

Follow these steps to find Ubuntu version information

  1. Open a Terminal by pressing Ctrl + Alt + T keys together on keyboard or navigating to the terminal in apps.
  2. Now execute this command lsb_release -a to display Ubuntu version.
lsb_release -a

Output:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Codename: bionic

You will get somewhat similar output, here Description as well as Relese shows your current Ubuntu version. As I am using Ubuntu 18.04.4 LTS.

You might have a question why Description says Ubuntu 18.04.4 while Release is 18.04. Whats the difference? The difference is 18.04 is the base image while the last 4 stands for the forth point release.

This forth point release means all the previous bug fixes, updates that were released for base image 18.04 will already be applied in this release. So when you do a clean new installation you have fewer updates to install.

Here Code-name Bionic stands for the name given to the release. This name is different for each version of Ubuntu and is allotted with the release.

If you don’t want to see all these details you can also see only Ubuntu verion by the command below.

lsb_release -d
Output;

Description: Ubuntu 18.04.4 LTS
