ubuntu version check

Knowing the version of Ubuntu installed on your system is crucial for ensuring compatibility with software, troubleshooting issues, and receiving updates. Whether you’re a beginner or an experienced user, this guide will show you how to quickly find out which version of Ubuntu you are using.

Why Checking Your Ubuntu Version is Important?

There are several reasons why you might need to check your Ubuntu version:

  • Software Compatibility: Some applications or packages may require specific Ubuntu versions to work correctly.
  • Security Updates: Knowing your version helps ensure you’re using the latest security patches.
  • System Troubleshooting: Certain issues may be version-specific, so knowing your version is essential for finding solutions.
  • Upgrading Ubuntu: To upgrade to a newer version, you first need to know your current version.

Now let’s look at how to check your Ubuntu version using different methods.

Method 1: Using the Terminal

The terminal is one of the most efficient ways to check your Ubuntu version. Follow these steps:

Step 1: Open the Terminal

Press Ctrl + Alt + T to open the terminal window.

Step 2: Run the Version Command

To check the version of Ubuntu, type the following command:

lsb_release -a

This command will display detailed information about your Ubuntu version. You should see output like this:


No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04 LTS
Release:        20.04
Codename:       focal

The key fields to look for are:

  • Description: This shows the version of Ubuntu you’re using, such as “Ubuntu 20.04 LTS”.
  • Release: This is the version number (e.g., 20.04, 22.04, etc.).
  • Codename: This is the codename associated with that version (e.g., focal, jammy, etc.).

Method 2: Using the /etc/os-release File

Another way to check the Ubuntu version is by checking the /etc/os-release file, which contains system information. Here’s how:

Step 1: Open the Terminal

Press Ctrl + Alt + T to open the terminal.

Step 2: Use the Cat Command

Run the following command to display the contents of the /etc/os-release file:

cat /etc/os-release

The output will show something like this:


NAME="Ubuntu"
VERSION="20.04 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
VERSION_ID="20.04"
VERSION_CODENAME=focal
UBUNTU_CODENAME=focal

Look for the VERSION field, which tells you your Ubuntu version (e.g., “20.04 LTS”).

Method 3: Using the Neofetch Tool

For those who like a more visually appealing way to display system information, the Neofetch tool can show your Ubuntu version along with other system details in a neat, terminal-friendly format.

Step 1: Install Neofetch

If you don’t already have Neofetch installed, open the terminal and run the following command to install it:

sudo apt install neofetch

Step 2: Run Neofetch

Once installed, you can display your system information, including your Ubuntu version, by typing:

neofetch

The output will display a variety of system information in a colorful format, including your Ubuntu version, kernel version, and more.

Method 4: Using the GUI (Graphical User Interface)

If you prefer not to use the terminal, you can also check your Ubuntu version using the graphical interface:

Step 1: Open Settings

Click on the “Activities” overview or the system menu and search for “Settings”.

Step 2: Go to the About Section

In the settings window, scroll down and click on the “About” section. You will see information about your system, including the version of Ubuntu you’re running.

Conclusion

Checking your Ubuntu version is simple and can be done in several ways, whether you prefer using the terminal or a graphical interface. Knowing your version helps you manage your system better, ensuring compatibility with software, receiving appropriate updates, and troubleshooting issues. By following any of the methods outlined above, you can quickly check your Ubuntu version and stay informed about your system’s current state.
