Ubuntu 26.04 LTS (codenamed Resolute Raccoon) was released on April 23, 2026. It brings major updates including Linux kernel 7.0, GNOME 50, improved security features, and better performance.
Upgrading from Ubuntu 24.04 LTS (Noble Numbat) to 26.04 LTS is a significant jump. While possible, the official smooth upgrade path opens after the first point release (26.04.1), expected in early August 2026.
Important: Who Should Upgrade & Who Should Wait
- You are on Ubuntu 25.10 (interim release)
- You are a developer, tester, or power user comfortable troubleshooting issues
- You need the latest kernel, security features, or software versions immediately
- You have a full backup and can reinstall if something goes wrong
- You run a production server or critical workstation
- You use proprietary drivers (NVIDIA, Wi-Fi, printers) that may break
- Your system has custom configurations or third-party PPAs
- You prefer maximum stability — wait for 26.04.1 (August 2026)
- You are not comfortable with command-line troubleshooting
Preparation Steps (Must Do Before Upgrading)
- Backup everything important
Usersync, Deja Dup, or an external drive to back up /home, documents, databases, and configuration files. - Update your current system completelysudo apt update && sudo apt upgrade -y
sudo apt dist-upgrade -y
sudo apt autoremove -y - Remove unnecessary packages to reduce risk.
- Disable third-party PPAs temporarily (or remove them if not essential).
- Check disk space — ensure you have at least 20–25 GB free on the root partition.
Method 1: Recommended Upgrade Using do-release-upgrade (After 26.04.1)
When 26.04.1 is released (expected August 2026), most users will see an upgrade notification. You can also trigger it manually:
Commands to run:
sudo do-release-upgrade
The tool will download packages, install them, and guide you through the process. Your system will reboot several times.
Method 2: Force Upgrade Right Now (Using -d flag)
If you want to upgrade immediately (not recommended for production systems):
The -d flag forces the upgrade to the development release.
Warning: This method may encounter bugs as the upgrade path is still being stabilized.
After Upgrade – What to Do Next
- Reboot your system and check
lsb_release -ato confirm the version. - Re-enable any disabled PPAs and reinstall proprietary drivers if needed.
- Update all applications: sudo apt update && sudo apt upgrade
- Test critical applications and services.
- If something breaks, you can use the Ubuntu 26.04 Live USB to repair or reinstall.
Common Issues & Tips
- NVIDIA drivers may need reinstallation after upgrade.
- Some custom configurations (especially in
/etc) may require manual merging. - If the upgrade fails, you can restore from backup or do a clean install.
Best Practice: For most users, wait for the official upgrade prompt after Ubuntu 26.04.1 releases in August 2026. This ensures a much smoother and safer experience.
Always back up your data before any major upgrade. A successful upgrade saves time, but a good backup saves everything.
