Tutorial Check Linux Ubuntu Version (Command Line and GUI)

Join us with this guide to learn how to check the Ubuntu version. The Command line (Terminal) enables you to check your running Ubuntu version quickly. To find your Ubuntu version, 4 different methods will be explained in this article. The other way to check the Ubuntu version is in the Gnome Desktop. Till the end, you will be an expert in all of them. Just continue reading.

How To Check Ubuntu Version Using Terminal

The first way is to check the Ubuntu version from the Command line which includes four methods itself. Several commands are available to be used to clarify the current version of Ubuntu you are running. Let’s discuss them all.

As you may know, accessing to Terminal (Command line) is possible by pressing Ctrl + Alt + T. Then, you are ready to use any one of the following methods and view your Ubuntu version.

1- lsb_release -a Command

The lsb_release command displays the information of Linux Standard Base (LSB) about the Linux and distribution details. This preferred method checks your Ubuntu version and works on both the desktop environment and all Ubuntu versions you are running. To use this command, just run:

lsb_release -a

Output

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.3 LTS
Release:    20.04
Codename:   focal

Once you type the command above, you will see the Ubuntu version in the description line and your LSB modules, and the codename for your distributor data.

However, it is possible to view the description line instead of printing all the information. To do this, run:

lsb_release -d

The output will be something like this:

Output

Description:    Ubuntu 20.04.3 LTS

2- /etc/lsb-release or /etc/os-release Command

The second command line is mostly used for older systems (Compatible with Ubuntu 16.04 and higher). If you are running an outdated version of Ubuntu, the /etc/lsb-release or /etc/os-release command is a better choice for you. /etc/os-release is a file that contains operating system identification data. To display the content of the file, you must use the ”cat” before the command.

cat etc/os-release

Obviously, running the command above will display a list of the number of your Ubuntu version and its release name. This command also gives you a few links to the Ubuntu website and resources that would be helpful. The output will be something like this:

Output

NAME="Ubuntu"
VERSION="20.04.3 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.3 LTS"
VERSION_ID="20.04.3"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=focal
UBUNTU_CODENAME=focal

As you see, the result of running the /etc/lsb-release command will include the release ID, description, and codename which means it will not show you the links and the Ubuntu version name.

3- /etc/issue File Checking

Till now, the first method was simpler than the second method. But if you need to view just the Ubuntu version, and you do not need to review the additional information about your system, use the second method. It is simpler than the two recently introduced methods. Showing your system identification data, the /etc/issue file is a text-based document.

Again, you need to enter ‘’cat’’ before the command. So, run:

cat /etc/issue

The output must be something like the below:

Output

Ubuntu 20.04.3 LTS \n \l

As you guess, you do not need to do anything more here. The series of numbers before LTS is your Ubuntu version.

4- hostnamectl Command

The 4^th and last method is used when you need to change the hostname of your system. But is also used to check the Ubuntu version. You can use it for Ubuntu 16.04 and newer versions. It shows you the Ubuntu version and machine ID. To use this command, run:

hostnamectl

Output

  Static hostname: linuxize
         Icon name: computer-vm
           Chassis: vm
        Machine ID: f1ce51f447c84509a86afc3ccf17fa24
           Boot ID: 2b3cd5003e064382a754b1680991040d
    Virtualization: oracle
  Operating System: Ubuntu 20.04.3 LTS
            Kernel: Linux 5.11.0-34-generic
      Architecture: x86-64

The command shows you both your Ubuntu version and your Ubuntu Linux kernel version. Now, you know how to check your Ubuntu version in 4 different methods in the command line.

How To Check Ubuntu Version in the GUI Settings

You can check your Ubuntu version in the GUI settings if you do not prefer to use the command line. Users who are getting used to working with the OS and its layout might prefer to choose this method, although it takes more time. Follow the below steps to use this method.

Step 1

In the bottom left of your screen, head to the icon of Show Application.

Step 2

Now, type ‘’Setting’’ into the search bar and click on it.

Step 3

Then, from the left menu, scroll to the bottom of the list of items and find the About tab. Now, you can see your Ubuntu version next to the OS Name heading.

As you see, we’re currently running Ubuntu 20.04.3 on our system.

That’s it! As easy as you saw.
