By the end of this guide, you'll be equipped with multiple ways to find your Ubuntu version, making it easier to troubleshoot problems, plan upgrades, and ensure software compatibility.

Let's dive in!

The Different Versions of Ubuntu

Ubuntu rolls out new versions approximately every six months. Each version has a unique code name, such as "Bionic Beaver" or "Focal Fossa." Besides these standard editions, Ubuntu also offers specialized flavors like Ubuntu Server, Ubuntu Mate, or Kubuntu. Although these flavors use different desktop environments, they share the core Linux kernel and foundational system.

But regardless of which flavor you’re using, identifying the underlying system version is key to managing your Linux environment effectively.

Why You Might Need To Check Your Ubuntu Version

You might wonder why it's so essential to know your operating system version. Here are some of the key reasons:

Checking Software Compatibility

Before installing new software, verifying compatibility with your Ubuntu version is critical. Newer applications might not support older releases, and the reverse can also be true. Knowing your version can help you avoid unnecessary troubleshooting.

Security Updates

Newer Ubuntu versions often include essential security patches. If you’re worried about vulnerabilities, checking your Ubuntu version ensures you have the most recent protections.

Troubleshooting Issues

When diagnosing system problems, knowing your exact Ubuntu version is invaluable. Many issues are specific to particular releases, and most tech support will need this information to assist you effectively.

Planning for Upgrades

Before you upgrade your system, it's wise to confirm that your current hardware can support the new features. Similarly, updating Ubuntu might be necessary to leverage new hardware upgrades.

How To Find Out Which Version Of Ubuntu You’re Using

Now, let’s get hands-on! Below are the top five methods to check your Ubuntu version using both GUI and command line techniques.

Method 1: Check Your Version Via The GUI Settings

If you prefer a more intuitive approach, you can check your Ubuntu version using the graphical user interface:

  1. Open Settings: Click on the system menu at the top-right corner and select "Settings."
  2. Navigate to About: Scroll down to the "About" section. Here, you’ll find details about your system, including the Ubuntu version.

This method is perfect for those uncomfortable with the command line. However, if you want a quicker approach, the terminal has you covered.

Method 2: The lsb_release -a Command

The lsb_release -a command is one of the simplest ways to find out your Ubuntu version through the terminal. Here’s how:

  1. Open Terminal: Press Ctrl+Alt+T to open the terminal.
  2. Type Command: Enter lsb_release -a and press Enter.
  3. Read Output: The terminal will display details about your distribution, including the version number.

This command works on most Linux distributions, making it versatile.

Method 3: The cat /etc/os-release Command

Another way to get version information is by querying the os-release file. Follow these steps:

  1. Open Terminal: Press Ctrl+Alt+T to access the terminal.
  2. Type Command: Type cat /etc/os-release and hit Enter.
  3. Read Information: The file contents will include the version name and number.

This method is straightforward and fetches information directly from the file system.

Method 4: Check Your /etc/issue File

The /etc/issue file contains a short system identification text. Here’s how you can access it:

  1. Open Terminal: Use Ctrl+Alt+T to open the terminal.
  2. Type Command: Input cat /etc/issue and press Enter.
  3. Read Output: The file will show the Ubuntu version.

This command provides a quick way to get your version number with minimal typing.

Method 5: Use The hostnamectl Command

While initially designed for managing hostnames, the hostnamectl command also reveals your Ubuntu version:

  1. Open Terminal: Hit Ctrl+Alt+T to open the terminal.
  2. Type Command: Enter hostnamectl and hit Enter.
  3. Review Information: The output will include the Ubuntu version along with other system details.
