Comprehensive Overview: Methods to Determine Your Ubuntu Version

There are several ways to determine which version of Ubuntu you are running, each catering to different preferences and levels of technical expertise. These methods range from simple GUI-based approaches to using powerful command-line tools. Here are some of the most reliable and straightforward methods:

1. Using the lsb_release Command

The lsb_release command is a standard tool in Ubuntu for displaying Linux Standard Base (LSB) information, including the distribution version. This is one of the most direct and accurate ways to find your Ubuntu version from the command line.

To use it, open your terminal and type:

lsb_release -a

This command will display detailed information, including the distributor ID, description, release number, and codename. The "Release" line will show the specific version of Ubuntu you are running, such as "20.04" for Ubuntu 20.04 LTS.

2. Checking /etc/os-release

The /etc/os-release file contains operating system identification data. It's a simple text file that includes the name, version, and other relevant details about your Ubuntu installation.

To view this file, use the cat command in your terminal:

cat /etc/os-release

The output will display several lines, including NAME, VERSION, ID, and VERSION_ID. The VERSION_ID field will show the Ubuntu version number, such as "22.04" for Ubuntu 22.04 LTS.

3. Using hostnamectl

The hostnamectl command is part of the systemd suite and provides system hostname and related information. It can also reveal the operating system version.

Open your terminal and type:

hostnamectl

This command will display various system details, including the operating system name and version under the "Operating System" line. For example, it might show "Ubuntu 20.04.5 LTS."

4. Checking /etc/issue

The /etc/issue file is another place where system information is stored. It typically displays a system identification message before the login prompt.

To view this file, use the cat command:

cat /etc/issue

The output will show a string that includes the Ubuntu version. However, note that this file is primarily intended for display purposes and might not always be accurate, especially if it has been modified.

5. Using the GUI: Settings App

For users who prefer a graphical interface, Ubuntu provides a simple way to check the version through the Settings app.

1. Open the Settings application. You can usually find it in the applications menu or by searching for "Settings."
2. Scroll down to the bottom of the sidebar and click on About.
3. In the About section, you will find the Ubuntu version listed next to "OS Name" or "Version."

This method is straightforward and requires no command-line knowledge, making it ideal for beginners.

6. Using the uname Command

The uname command provides information about the kernel name, version, and other kernel-related details. While it doesn't directly show the Ubuntu version, it can provide clues, especially when combined with other methods.

To use it, open your terminal and type:

uname -a

The output will display kernel information, including the kernel version number. While this doesn't give you the Ubuntu version directly, knowing the kernel version can be helpful in some contexts, such as when troubleshooting driver compatibility issues.
