Check Ubuntu Version: A Step-by-Step Guide to Find Out Your OS Version

Checking your Ubuntu version is a simple task that can be completed in just a few steps. Knowing your Ubuntu version is important for system updates, security patches, and software compatibility. In this article, we’ll walk you through how to easily find out which Ubuntu version you’re running.

Step by Step Tutorial: Check Ubuntu Version

Before we dive into the steps, it’s important to understand that checking your Ubuntu version helps you to keep your system up to date and secure. Let’s get started!

Step 1: Open the Terminal

Press Ctrl + Alt + T to open the Terminal.

The Terminal is the command-line interface in Ubuntu that allows you to interact with your system. Think of it as a powerful tool to execute various tasks.

Step 2: Enter the Command

Type lsb_release -a and press Enter.

This command is short for Linux Standard Base, and the -a flag stands for ‘all’, which means it will display all the LSB (Linux Standard Base) information.

Step 3: Read the Output

Look for the line that starts with Description: or Release:.

The output will display several lines of information, but the one you’re interested in will tell you the release number of your Ubuntu installation.

After completing these steps, you should now know the version of Ubuntu you are running. This information can help you with troubleshooting, software installation, and ensuring that you have the latest security updates.

Tips for Checking Ubuntu Version

  • Remember that Ubuntu releases have support cycles, so knowing your version is crucial for maintaining support.
  • You can also use uname -r to check your Linux kernel version, which is different from your Ubuntu version but still good to know.
