Introduction

Have you ever needed to find out which version of Linux you're working with? Whether you're troubleshooting an issue, ensuring compatibility with specific software, or planning a hardware upgrade, knowing your operating system’s version can be crucial. This is especially relevant for Ubuntu users, although these methods can work for most Linux distributions.

Knowing your Linux version can help you troubleshoot issues, avoid compatibility problems, and plan hardware upgrades. Additionally, it can aid in maintaining good security practices by ensuring you have the latest updates.

In this detailed guide, we’ll walk you through different methods to identify your Ubuntu version in just a few minutes. From the graphical user interface (GUI) for beginners to more advanced command-line options, we've got you covered.

The Different Versions Of Ubuntu

Ubuntu, one of the most popular Linux distributions, regularly releases updates. Approximately every six months, a new version is rolled out, each with its unique code name. These versions aren't just minor updates but often carry significant changes that can affect compatibility with software and hardware.

Interestingly, Ubuntu is available in various flavors, which are essentially different desktop environments built upon the same underlying Ubuntu system. Despite these variations, they all share the same Linux kernel and core operating system. It is this core system's version that we're interested in finding.

Why You Might Need To Check Your Ubuntu Version

You might be wondering why it's important to know your Ubuntu version. Here are a few key reasons:

Checking Software Compatibility

Software applications are often designed and tested for specific versions of operating systems. Running newer software on older versions of Ubuntu might result in compatibility issues. The same can apply when trying to update existing applications.

Security Updates

New versions of Ubuntu often come with patches for security vulnerabilities. Ensuring you're running the latest version can protect your system from potential threats.

Troubleshooting Issues

When resolving problems on your device, knowing your exact Ubuntu version can be crucial. Many issues are version-specific, so tech support will often ask for this information.

Planning for Upgrades

Older devices may not support the technical requirements of the latest Ubuntu versions. Knowing your current version can help you determine if your system can handle an upgrade or if you need to update your hardware.

Harnessing New Hardware

If you're upgrading hardware, you may need the latest Ubuntu version to ensure full compatibility and take advantage of new features.

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

Let's dive into the methods for checking your Ubuntu version, ranging from user-friendly GUI options to more technical command-line approaches.

Method 1: Check Your Version Via The GUI Settings

The easiest and most user-friendly way to check your Ubuntu version is through the GUI. Here's how:

  1. Open the "Settings" app from the system menu.
  2. Navigate to the "About" section.
  3. Here, you will see the version information under the "OS Name" and "OS Version" fields.

This method is perfect if you're not comfortable with the command line and prefer a graphical interface.

Method 2: The lsb_release -a Command

For those more comfortable with the terminal, the lsb_release command provides detailed information about your Ubuntu version. Follow these steps:

  1. Open your terminal.
  2. Type lsb_release -a and press Enter.

This command will display your Ubuntu version alongside other details like the distributor ID and codename.

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

You can also check your Ubuntu version by querying the system files that store this information. Here’s how to do it:

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

This command will display system information including the Ubuntu version, in a structured format.

Method 4: Check Your /etc/issue File

Another way to find your Ubuntu version is by checking the /etc/issue file. Use the following steps:

  1. Open your terminal.
  2. Run the command cat /etc/issue.

This will print out the version number alongside a brief system description.

Method 5: Use The hostnamectl Command

The hostnamectl command is primarily used for setting or changing the system's hostname but can also provide system information, including the Ubuntu version. Here's how:

  1. Open your terminal.
  2. Enter the command hostnamectl.

Among other details, this will display your operating system version.
