So, how can you find out which version of Ubuntu you're running? There are several easy methods to determine your Ubuntu version.
1. Using the Terminal
The command line is a powerful tool for managing your Ubuntu system, and it offers a straightforward way to check your version.
-
Open a terminal: You can access the terminal by pressing Ctrl+Alt+T or by searching for "Terminal" in your application menu.
-
Run the command: In the terminal window, type the following command and press Enter:
lsb_release -a
- Interpret the output: The command will display detailed information about your Ubuntu system, including the version, codename, and distribution identifier. The key line to focus on is the one that says "Description:". The string after "Description:" will specify your Ubuntu version.
2. Using the "About" System Information
The graphical user interface (GUI) also provides a convenient way to access your system information, including the Ubuntu version.
-
Open the "About" window: You can find this by clicking the "Activities" icon in the top-left corner of your screen and searching for "About".
-
Locate the version information: Once you've opened the "About" window, look for a section that displays your "Ubuntu Version". This will tell you the exact Ubuntu version you're running.
3. Checking the System Files
If you're comfortable navigating your file system, you can also check your Ubuntu version by examining the "lsb-release" file.
-
Open a file manager: You can access it by clicking the "Files" icon in the dock or by searching for "File Manager" in your application menu.
-
Navigate to the file: Go to the following location:
/etc/lsb-release
- Examine the file: Open the "lsb-release" file with a text editor. You'll find the "DISTRIB_DESCRIPTION" variable, which will contain your Ubuntu version.
Understanding Ubuntu Release Names
Ubuntu versions are often referred to by their code names, which are catchy words based on animals. For example, Ubuntu 22.04 is nicknamed "Jammy Jellyfish". Knowing the code name can be helpful for identifying specific versions and searching for information online.
Tips for Keeping Your Ubuntu Up-to-Date
-
Regularly check for updates: Ubuntu automatically checks for updates and notifies you when they're available. It's essential to install these updates promptly to ensure your system's security and stability.
-
Use the Software Updater: You can find the "Software Updater" in your application menu. This tool will help you easily install available updates.

Consider upgrading to a newer version: Ubuntu releases new versions regularly. Upgrading to a newer version can give you access to the latest features and security updates.
