Check Ubuntu Versions Easy Methods

In this tutorial, we will go over the easiest methods to check Ubuntu version from the terminal. You can use any of the methods below depending on what you need. The outputs that the commands provide are very basic, but at the end of the tutorial, we’ve shown some APT packages that give the version information, in a really beautiful ASCII format.

Files That Contain Ubuntu Version Details

There are a few configuration files that contain details of the version and the release information of the Linux distribution you’re on. So, if you’re looking for files that can provide you with the required details, keep reading.

1. LSB-Release File

LSB stands for Linux Standard Base. The lsb-release file is located in /etc/lsb-release directory. We can run the cat command to output the contents of this file.

root@ubuntu:~# cat /etc/lsb-release

2. Issue File in Ubuntu

The /etc/issue file contains information that you see right before a terminal prompt is displayed after logging in.

This file is editable by users to allow the display of a custom message before the login prompt is displayed. But if you’re sure there have been no manual changes to the file, it will contain the version of the distribution.

root@ubuntu:~# cat /etc/issue
Ubuntu 18.04.3 LTS \n \l

3. OS-Release File

Another file that offers detailed information about Ubuntu versions is the OS-Release file.

root@ubuntu:~# cat /etc/os-release

PRETTY_NAME="Ubuntu 18.04.3 LTS"

These are packages that you need to install using the apt install command before they become available.

1. screenfetch

The first command is the screenfetch command. Below is an example of what the default output looks like.
