How to check your Ubuntu version in the command line?

Checking your Ubuntu version employing the command line is quick and efficient. Here are four methods to help you find Linux version, verify your Linux OS system, or check the Linux kernel version.

1. Employ the lsb_release -a command

The easiest way to check Ubuntu version is by using the lsb_release -a command. This command displays detailed information about your Linux distribution, making it useful when you need to know the Ubuntu version you’re running.

To use it:

lsb_release -a

This command shows the Linux OS version, codename, and description of the system. If you’re wondering how to see the Linux OS, this is a straightforward option.

2. Employ the /etc/lsb-release or /etc/os-release command

You can also check the Linux version by reading the /etc/lsb-release or /etc/os-release files. These files store details about the OS and are great for confirming your Linux Ubuntu version.

To read these files:

cat /etc/lsb-release

Or:

cat /etc/os-release

These commands provide essential details about the Linux OS version and are helpful when verifying the Debian_variant or checking your Linux distro against a chart of all Linux versions.

3. Check the /etc/issue file

Another way to show Linux version is by viewing the /etc/issue file. This file contains a brief description of your operating system.

Run this command:

cat /etc/issue

This method is quick and provides an overview of your Linux OS system, allowing you to check Linux version at a glance.

4. Use the hostnamectl command

The hostnamectl command gives you both system and OS details. It’s particularly useful if you want to know how to verify the version of Linux kernel as well as the Ubuntu release.

Use this command:

hostnamectl

It displays your Ubuntu show version, Linux kernel version, and hardware details, helping you determine the exact Linux OS version you are running.

How to Check Ubuntu Version via Graphical Interface

In case you are not comfortable employing the command line, you can easily check your Ubuntu version via the graphical interface (GUI). This method provides a simple way to see the Linux OS version, making it beginner-friendly. Whether you’re looking to confirm your Ubuntu version or understand which Linux OS you’re using, the GUI can show these details without needing terminal commands.

Here’s how to check Linux version using the Ubuntu desktop interface. It’s a straightforward way to find the Linux OS version without technical expertise.

How to Check Your Ubuntu Version in the GUI Settings?

To check the version of your Ubuntu through the system settings, follow these steps:

1. Open the Settings Menu: Click on the system menu at the top-right end of your screen. Select the “Settings” option to open the configuration panel. This is the starting point to find Linux version via the GUI.
2. Navigate to ‘About’ Section: Scroll down and find the “About” section in the left-hand panel. This section gives you essential system information, including your Linux version and other system details.
3. View Your Ubuntu Version: In the “About” section, you’ll see the Ubuntu show version, including the version number and Linux OS version. You can also see information about your hardware and kernel version, useful when checking the Linux kernel version.
4. Verify the Kernel Version: If you also want to check the version of Linux kernel, this same window provides the details. This is especially helpful if you are trying to compare it with a chart of all Linux and kernel base versions or need to determine compatibility with software and drivers.
