Imagine you're troubleshooting an issue on your Ubuntu system or planning to install new software. One of the first pieces of information you might need is your Ubuntu version. Knowing your version can be crucial for compatibility checks, security updates, and troubleshooting. This guide will walk you through five simple methods to determine your Ubuntu version, whether you're comfortable using the command line or prefer a graphical interface.

By the end of this post, you'll be equipped with the knowledge to quickly identify your Ubuntu version, making system management tasks much more straightforward.

The Different Versions of Ubuntu

Ubuntu releases occur twice a year, in April and October, typically introducing new features, bug fixes, and security improvements. Each release is represented by a version number and a code name. For instance, "Ubuntu 20.04 LTS" is a version released in April 2020, with LTS standing for Long-Term Support, meaning extended support and updates for five years.

Ubuntu variations, such as Kubuntu, Xubuntu, and Lubuntu, provide different desktop environments while sharing the same core system. This shared base ensures that the methods we'll discuss can be applied across these variations to find the version number.

Why You Might Need to Check Your Ubuntu Version

Checking Software Compatibility

Certain software applications may only be compatible with specific Ubuntu versions. Verifying your version number ensures you can avoid compatibility issues, making it easier to manage software installations and updates.

Security Updates

Regular updates are released to address security vulnerabilities. Knowing your current version helps determine whether you're protected against recent threats or if you need to update your system.

Troubleshooting Issues

When encountering problems with your Ubuntu system, it's helpful to know your version number. Many issues are version-specific, and tech support or online forums will often ask for this information to provide accurate help.

Planning for Upgrades

Before upgrading your Ubuntu system or hardware, confirming your current version is essential. Not all hardware may be compatible with the latest Ubuntu releases, so this step can help avoid potential problems.

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

Here are five easy methods to check your Ubuntu version, ranging from graphical user interface (GUI) approaches to command-line techniques.

Method 1: Check Your Version via the GUI Settings

The most user-friendly way to check your Ubuntu version is through the graphical settings interface. Here’s how to do it:

  1. Open the "Settings" from the application menu.
  2. Navigate to the "Details" or "About" section.
  3. Look for the "OS Name" and "OS Version" fields.

This method is perfect for those who prefer a visual approach and avoids the need for command-line knowledge.

Method 2: The lsb_release -a Command

Using the command line can be quicker for seasoned users. The lsb_release -a command provides detailed information about your Ubuntu system. Here's how to use it:

  1. Open the Terminal.
  2. Type lsb_release -a and press Enter.

You'll see various details about your Linux distribution, including the description, release number, and codename.

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

The /etc/os-release file contains information about your operating system. You can quickly access this using the cat command:

  1. Open the Terminal.
  2. Type cat /etc/os-release and press Enter.

This will display the system details, including the Ubuntu version.

Method 4: Check Your /etc/issue File

The /etc/issue file is another location where version information is stored. This method involves another simple command:

  1. Open the Terminal.
  2. Type cat /etc/issue and press Enter.

The command will return a line that includes your Ubuntu version.

Method 5: Use the hostnamectl Command

The hostnamectl command is primarily used for changing your system’s hostname but can also provide version details:
