Introduction
Have you ever found yourself needing to know which version of Ubuntu you're working with? Whether it's troubleshooting an issue, ensuring compatibility with specific software, or planning a hardware upgrade, knowing the version of your operating system can be vital. This need is especially pertinent for Ubuntu users, although the methods we'll discuss can be applied to most Linux distributions.
From security updates to software compatibility, verifying your Ubuntu version is fundamental. This guide aims to show you how to identify your Ubuntu version through various methods quickly.
Let's dive in!
The Different Versions Of Ubuntu
Ubuntu releases a new version roughly every six months, each one bringing updates and improvements. Each release is given a unique code name that follows a specific format: an adjective paired with an animal, both starting with the same letter. These code names follow the alphabetical order, making it easy to predict future names.
Although there are multiple flavors of Ubuntu, all versions share the same kernel and core operating system. What differentiates them is the desktop environment wrapped around the base system. Understanding your specific Ubuntu version involves diving into this core system.
Why You Might Need To Check Your Ubuntu Version
Software Compatibility
Software often depends on the operating system version for compatibility. Running newer software on older versions—or vice versa—can lead to issues. A simple version check can help avoid these problems.
Security Updates
New Ubuntu versions often come with patches for security vulnerabilities. If you are concerned about a specific threat, confirming that your system is up-to-date is crucial.
Troubleshooting Issues
Various issues can be version-specific. When seeking help or troubleshooting problems, providing your Ubuntu version can be a critical piece of information for tech support.
Planning for Upgrades
If you're considering upgrading your system, checking the current version is a good starting point. Some older devices might not support newer versions, so knowing what you currently have can guide you on the best upgrade path.
How To Find Out Which Version Of Ubuntu You’re Using
Enough theory—let's get your Ubuntu version number. Here are five methods, ranked from the most user-friendly to the slightly more technical.
Method 1: Check Your Version Via The GUI
This is the easiest method for users who prefer graphical user interfaces over command lines:
- Open the "Settings" app by clicking the gear icon.
- Navigate to the "Details" section. Here, you will find your version number listed under "OS Name."
This approach is perfect for those less comfortable with scripting and Linux commands.
Method 2: The lsb_release -a Command
The lsb_release command provides information about the Linux distribution you are using, including its version.
- Open your Terminal (Ctrl+Alt+T).
- Type
lsb_release -aand press Enter.
You will see detailed information about your Ubuntu version, including the codename.
Method 3: The cat /etc/os-release Command
Ubuntu stores version information in specific files. By querying these files, you can easily retrieve your version number.
- Open your Terminal.
- Run the command
cat /etc/os-release.
This will display various details about your operating system, including the version.
Method 4: Check Your /etc/issue File
Another file that holds version information is the /etc/issue file.
- Open your Terminal.
- Type
cat /etc/issueand press Enter.
This command will return the Ubuntu version in a straightforward format.
Method 5: Use The hostnamectl Command
The hostnamectl command is generally used for managing system hostnames but can also reveal critical system information including the Ubuntu version.
- Open your Terminal.
- Execute
hostnamectl.
Look for the "Operating System" line, which will provide you with the version number.
