EOL (End of Life) Version List

Upgrade Path Guide

Ubuntu supports upgrading directly from one LTS version to the next, but does not support skipping versions.

Supported Upgrade Paths

20.04 LTS → 22.04 LTS → 24.04 LTS → 26.04 LTS

Each version can only upgrade to the next LTS:

Upgrade Commands

# Ensure the current system is fully updated
sudo apt update
sudo apt full-upgrade
sudo reboot
 
# Begin upgrading to the next LTS version
sudo do-release-upgrade
 
# "No new release found"? LTS systems are only offered the next LTS once its .1 point release is out.
# Don't use -d: it upgrades to the release still in development.

Pre-upgrade Notes

1. Back up all important data — unexpected issues may occur during the upgrade
2. Record installed third-party PPAs — PPAs will be disabled during upgrade
3. Check third-party software compatibility — ensure critical software supports the new version
4. Reserve enough disk space — the upgrade process downloads a large number of packages
5. Server upgrades are best done via SSH — the upgrade tool automatically opens a backup SSH port (1022)

Check Your Current Version

# Check Ubuntu version
lsb_release -a
 
# Check kernel version
uname -r
 
# Check detailed system information
cat /etc/os-release
 
# Check if a version upgrade is available
sudo do-release-upgrade --check-dist-upgrade-only

Version Selection Recommendations

• Desktop users: Always use the latest LTS version (currently 26.04) for the latest hardware support and software versions
• Server/Production: 24.04 LTS is still in standard support, so you can migrate on your own schedule; upgrades to 26.04.1 were enabled on September 29, 2026, so sudo do-release-upgrade is all you need
• Developers/Early adopters: Can use the latest short-term release (e.g., 26.10), but note only 9 months of support; 25.10 reached end of life in July 2026
• Enterprise deployment: Use Ubuntu Pro for up to 10 years of support

Plan your version upgrade strategy wisely to enjoy new features and security updates while maintaining system stability.
