Want to know which Ubuntu version runs on your computer? This guide shows you the easiest ways to find out. You’ll learn quick methods that work on any Ubuntu system.
Why Knowing Your Ubuntu Version Matters
Your Ubuntu version affects many things on your computer.
Software installation – Programs need specific versions to work correctly. Installing software on the wrong version leads to errors and crashes.
Security updates – Older versions stop receiving protection from hackers. You must know if your system still gets these critical updates.
Getting support – When you post questions in online forums, helpers need your version number. This information speeds up solutions to your problems.
Troubleshooting – Fixing software issues often requires version-specific steps. The wrong instructions can make problems worse.
Understanding Ubuntu’s Version System
Ubuntu uses numbers that tell you when each version came out.
The format looks like YY.MM. The first pair shows the year, the second shows the month. Ubuntu 24.04 arrived in April 2024. Ubuntu 22.10 launched in October 2022.
Every release gets a creative name with matching first letters. You might see names like Jammy Jellyfish, Noble Numbat, or Focal Fossa.
LTS and Regular Versions Explained
Ubuntu comes in two flavors:
LTS releases appear every two years. These Long-Term Support versions get five years of updates. Servers and businesses prefer these stable versions.
Standard releases launch twice yearly. They bring the newest features, but only receive nine months of support. Tech enthusiasts who want cutting-edge tools choose these versions.
Method 1: The lsb_release Command (Quickest Option)
This terminal command gives you instant results. It works on every Ubuntu installation.
Basic Steps
Hit Ctrl + Alt + T on your keyboard. Your terminal window opens. Type this command:
lsb_release -a
Press Enter. The screen displays:
- Version number (like 22.04)
- Full name including LTS status
- Release codename
- Distributor information
A message might say “No LSB modules are available.” Don’t worry about this warning. Your command still works perfectly.
Specific Information Options
Need just one piece of data? These variations help:
Description only:
lsb_release -d
Output shows: Description: Ubuntu 24.04.1 LT.S
Version number only:
lsb_release -r
You see: Release: 24.04
Codename only:
lsb_release -c
Result displays: Codename: nobl.e
No admin password needed for these commands. They run instantly on desktops and servers alike.
Method 2: Reading Built-in System Files
Ubuntu stores version details in text files. You can peek inside these files anytime.
The os-release File
Enter this command:
cat /etc/os-release
Multiple lines appear with system information:
- NAME: Your distribution name
- VERSION: Complete version with codename
- VERSION_ID: Numbers only
- PRETTY_NAME: Formatted version string
The lsb-release File
This file keeps things simple:
cat /etc/lsb-release
Four clean lines show up:
- DISTRIB_ID=Ubuntu
- DISTRIB_RELEASE=22.04
- DISTRIB_CODENAME=jammy
- DISTRIB_DESCRIPTION=”Ubuntu 22.04.3 LTS”
The issue File
Check what your login screen displays:
cat /etc/issue
Want cleaner output? Try:
cat /etc/issue.net
These file methods work on minimal installations that lack extra packages.
Method 3: The hostnamectl Command
One command reveals multiple system details together.
Type in your terminal:
hostnamectl
Information appears about:
- Computer hostname
- Operating system version
- Kernel release number
- System architecture (32 or 64-bit)
- Virtualization status
System administrators love this command. It shows everything needed for software development and troubleshooting in one place.
Method 4: Graphical Settings Menu (No Terminal Required)
Desktop users can find version info through point-and-click menus.
GNOME Desktop Steps (Standard Ubuntu)
Follow this path:
- Click Activities at screen top-left
- Search box appears – type Settings
- Click the Settings gear icon
- The left sidebar shows options
- Scroll down and select About
- OS Name shows your version
The About screen also reveals processor type, memory amount, disk space, and graphics details.
Alternative Desktop Environments
Other desktops organize menus differently:
KDE Plasma: System Settings → About This System Xfce: Settings Manager → About LXQt: System Settings → About
Look for “About” or “System Information” sections in your settings area.
Checking Ubuntu in WSL (For Windows Users)
Windows users running Ubuntu through WSL have special checking methods. For more information on OS systems, you can explore additional resources.
Inside the Ubuntu Terminal
Launch your Ubuntu app from Windows. Standard Ubuntu commands work normally:
lsb_release -a
Or view system files:
cat /etc/os-release
From Windows Command Line
Check without entering Ubuntu. Open PowerShell with admin rights. Run:
wsl –list –verbose
Short version works too:
wsl -l -v
All installed distributions appear with their running status.
Direct Command Execution
Execute Ubuntu commands straight from Windows:
wsl -d Ubuntu lsb_release -a
Replace “Ubuntu” with your actual distribution name for accuracy.
Finding System Architecture (32-bit vs 64-bit)
Software packages differ between architectures. Knowing yours prevents installation mistakes.
Using uname
Type this simple command:
uname -m
Results mean:
- x86_64: 64-bit system
- i686 or i386: 32-bit system
More comprehensive details appear with:
uname -a
The arch Command
Even simpler approach:
arch
Just your architecture prints out.
Processor Capabilities
See what your CPU handles:
lscpu
Find the CPU op-mode(s) line. Both modes listed mean your processor supports 64-bit. Only a 32-bit listing means hardware limitations exist.
Server Version Checking via SSH
Remote server management requires different approaches.
Secure Shell Connection
Connect to your remote machine:
ssh username@server-ip-address
Enter your actual login credentials and IP address.
Version Commands After Login
Once connected, any standard command works:
lsb_release -a
Single line output option:
lsb_release -ds
Multi-Server Checking
Test many servers without individual logins:
ssh username@server-ip “lsb_release -ds”
Connection happens, version displays, and the session closes automatically.
Kernel Version Information
Your kernel version differs from the Ubuntu version. The kernel forms Linux’s foundation.
Display Current Kernel
Simple command shows kernel:
uname -r
Example output: 5.15.0-91-generic
Numbers break down as:
- 5.15.0: Main kernel version
- 91: Ubuntu’s patch number
- generic: Kernel flavor type
Importance of Kernel Version
Newer kernels support modern hardware better. Some software requires specific kernels. Both version numbers help diagnose compatibility problems.
Visual System Information Tools
Fun tools display your system specs with style.
Installing neofetch
Neofetch creates ASCII art alongside system details.
Get it installed:
sudo apt update
sudo apt install neofetch
Run the program:
neofetch
Screen shows:
- Ubuntu logo in text characters
- Version and kernel numbers
- Processor and graphics info
- Memory and storage stats
- System uptime
The screenfetch Alternative
Similar tool with different styling:
sudo apt install screenfetch
screenfetch
Both programs make system information look appealing. Many users add them to startup scripts for automatic display.
Solving Common Issues
Problems sometimes occur when checking versions. Here are fixes.
Missing lsb_release Command
Basic installations might lack this tool. Install the package:
sudo apt update
sudo apt install lsb-release
The alternative method works without installation:
cat /etc/os-release
LSB Modules Warning
This harmless warning means developer libraries aren’t installed. Ignore it safely or install extras:
sudo apt install lsb-core
Most people never need these additional components.
Version Mismatch Between Methods
Settings menus sometimes show abbreviated versions. Terminal commands provide complete version strings, including point releases. Trust the terminal output for accuracy.
WSL Problems in Windows
Update WSL if commands fail:
wsl –update
Restart the subsystem:
wsl –shutdown
Version Management Best Practices
Regular Version Audits
Check monthly to ensure:
- Security updates still arrive
- Support hasn’t expired
- All systems match expected versions
Documentation Habits
Record which versions run where. This helps during:
- System upgrades
- Problem diagnosis
- Team coordination
Security Alert Subscriptions
Subscribe to Ubuntu Security notices. Critical patches need immediate attention.
Upgrade Planning
Mark these support end dates:
- Ubuntu 20.04 LTS: April 2025
- Ubuntu 22.04 LTS: April 2027
- Ubuntu 24.04 LTS: April 2029
Plan migrations before support expires.
