How to Prepare for Ubuntu 26.10 'Stonking Stingray': A Planner's Guide

Introduction

Planning for a new Ubuntu release is like gearing up for a major upgrade—you want to be ready when the big day arrives. Ubuntu 26.10, codenamed Stonking Stingray, is set to launch on October 15, 2026, with a feature freeze on August 10, 2026. These dates, however, are tentative and subject to change as development progresses. To help you stay organized and avoid last-minute surprises, this step-by-step guide walks you through everything you need to do—from understanding the schedule to updating your system safely. Whether you're a seasoned Linux enthusiast or a curious newcomer, follow these steps to make the most of Ubuntu 26.10.

What You Need

• A computer currently running Ubuntu (preferably an LTS or a recent interim release).
• Stable internet connection for downloading updates and the new ISO.
• Backup tool (e.g., Deja Dup, Timeshift, or manual copy) to protect your data.
• At least 25 GB free disk space (recommended for a clean install or upgrade).
• Patience and a willingness to read official release notes when they become available.

Step 1: Mark Key Dates in Your Calendar

Start by adding the two critical milestones to your planner or digital calendar:

• Feature Freeze: August 10, 2026 – After this date, no new features are introduced; only bug fixes and stability improvements are allowed. This is the point where you can start testing beta versions without worrying about major changes.
• Final Release: October 15, 2026 – The stable ISO becomes available for download and upgrade via do-release-upgrade.

Remember that these dates are tentative. Canonical may adjust them if development hits snags. Check the Tips section for how to stay updated on schedule changes.

Step 2: Back Up Your System

Before any upgrade, protect your personal files and system settings. Use a reliable backup tool like Deja Dup (for home directories) or Timeshift (for system snapshots). If you prefer manual backups:

1. Copy essential folders (Documents, Pictures, Music) to an external drive or cloud service.
2. Export a list of installed packages with dpkg --get-selections > package-list.txt.
3. Backup configuration files from /etc if you've made custom changes (optional but recommended).

Having a restore point means you can roll back if the upgrade doesn't go smoothly.

Step 3: Update Your Current Ubuntu Release

A week or two before the final release, ensure your current Ubuntu version is fully up-to-date. Open a terminal and run:

sudo apt update && sudo apt upgrade -y

This reduces the risk of conflicts during the major upgrade. If you're on an older release (e.g., 24.04 LTS), you may need to upgrade stepwise to 24.10 or 25.04 first—check the official upgrade path.

Step 4: Check Hardware Compatibility

New releases sometimes drop support for older hardware or introduce driver changes. Before the feature freeze, test your system's compatibility:

• Visit the Ubuntu Certified Hardware database to see if your laptop or desktop is listed.
• Try a live USB of the Ubuntu 26.10 daily build (available after the feature freeze) to verify that Wi-Fi, graphics, and sound work.
• Install any proprietary drivers (e.g., NVIDIA) that might require updates.

Step 5: Monitor the Development Cycle

After the feature freeze, canonical releases beta and release candidate images. If you're comfortable with testing, download the beta (around late August) to get a head start. To stay informed:

• Subscribe to the Ubuntu Blog for official announcements.
• Follow the Ubuntu Discourse for developer discussions.
• Set a reminder to check the official release schedule page (if it exists).

Step 6: Prepare for the Upgrade (Post-Release)

Once October 15 arrives, you can upgrade via two methods:

1. In-Place Upgrade: Run sudo do-release-upgrade -d (the -d flag is needed for non-LTS interim releases) or use the Software Updater GUI. This keeps your applications and settings intact.
2. Clean Install: Download the ISO from ubuntu.com/download and create a bootable USB using Rufus (Windows) or Startup Disk Creator (Linux). Back up data first, as this erases the drive.

If you're using LTS, consider waiting a few weeks post-release for any critical bug fixes to land.

Step 7: Test and Troubleshoot

After upgrading, run a quick sanity check:

• Verify the version: lsb_release -a should show Ubuntu 26.10.
• Test your daily apps (browser, office suite, development tools).
• Check for missing drivers or broken dependencies with sudo apt --fix-broken install.
• If something goes wrong, boot from a live USB to recover files or use Timeshift to restore your previous snapshot.

Tips for a Smooth Experience

• Don't rush the upgrade – Wait at least a day after the official release to let early adopters find any showstoppers.
• Use a separate partition or virtual machine for testing if you rely on your computer for work.
• Join community forums like Ask Ubuntu or r/Ubuntu to report issues and get help.
• Keep notes of any customizations you made so you can reapply them after the upgrade.
• Automatic updates will not push an interim release upgrade by default; you must initiate it manually.

With these steps, you're ready to embrace Ubuntu 26.10 Stonking Stingray with confidence. Happy upgrading!
