In this guide, I will show you how you can easily check which version of Ubuntu you are currently running on your machine. There are 2 main ways you can achieve this

1. Using the Terminal
2. Using the GUI

So let's get started and see how you can check which version of Ubuntu runs on your machine. But, Today I will be showing you on how to check ubuntu version using command line only.

Using Terminal

To check the version, Open your terminal and run the following command.

lsb_release -a

Output

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.5 LTS
Release:        16.04
Codename:       xenial

To be more specific you can also run

lsb_release -r

Output

Release:        16.04

Another way you can retrieve the version of your Ubuntu system is by running

cat /etc/lsb-release

Output

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS"

To gather more detailed information run

cat /etc/*release

Output

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.5 LTS"

To get information about the kernel and architecture run

uname -a

Also, the hostnamectl command can help you get the version of Ubuntu you are running

hostnamectl

This will give more detailed information such as Operating System, kernel, Architecture and in case the system is virtualized, it will display virtualization type and chassis.

Lastly, you can run this command on Terminal to give you the version of Ubuntu that you are running.

Output
