How to Check Ubuntu Version in Linux
Checking the version of Ubuntu installed on your Linux system is an essential task for various reasons. Whether you are troubleshooting issues, looking for compatibility with software, or simply curious about the version you are running, knowing your Ubuntu version is crucial. In this article, we will guide you through the process of checking the Ubuntu version in Linux.
Using the System Information Command
One of the simplest ways to check your Ubuntu version is by using the `lsb_release` command. This command is part of the `lsb-release` package, which provides basic information about the Linux distribution. Here’s how to use it:

2. Type the following command and press Enter:
“`
lsb_release -a
“`
3. The output will display detailed information about your Ubuntu version, including the release ID, codename, and distribution description.
Using the cat Command
Another method to check your Ubuntu version is by using the `cat` command to read the contents of the `/etc/os-release` file. This file contains various operating system-related information, including the version and codename. Follow these steps:
1. Open a terminal window.
2. Type the following command and press Enter:
“`
cat /etc/os-release
“`
3. Look for the “VERSION” and “ID” lines in the output. The “VERSION” line will display the Ubuntu version, while the “ID” line will show the distribution ID (e.g., Ubuntu).
Using the hostnamectl Command
The `hostnamectl` command is a more recent utility introduced in Ubuntu 16.04. It provides system information, including the OS version. To check your Ubuntu version using `hostnamectl`, follow these steps:
1. Open a terminal window.
2. Type the following command and press Enter:
“`
hostnamectl
“`
3. Look for the “Operating System” section in the output. The “Operating System” line will display the Ubuntu version and codename.
Conclusion
Knowing your Ubuntu version is essential for various reasons, and there are several methods to check it. By using the `lsb_release`, `cat`, or `hostnamectl` commands, you can quickly and easily determine the version of Ubuntu installed on your Linux system. These methods are simple to follow and will help you keep your system up-to-date and troubleshoot any issues that may arise.
