Ubuntu 26.10 Snapshot 2 Arrives with Updated Image Structure and Testing Improvements
The second development snapshot of Ubuntu 26.10, also known as “Stonking Stingray”, is now available for testing. This release is part of the four planned snapshot builds leading up to the final Ubuntu 26.10 launch scheduled for October.
Like the first snapshot, this version is mainly aimed at developers, testers, and community members who want to help identify issues before the stable release. For everyday users, there are currently few visible changes that would make switching from an existing system worthwhile.
Ubuntu developer Utkarsh Gupta announced the release and highlighted an important infrastructure update that affects how installation images are accessed. The change does not modify the operating system images themselves, but it changes the directory structure used to download them.
Canonical has recently reorganized the Ubuntu CD image server to create a more consistent layout across Ubuntu editions. Desktop images now follow the same structure already used by official Ubuntu flavours by being placed inside a dedicated distribution folder.
Previously, Ubuntu desktop images were stored directly under a release directory, such as:
cdimage.ubuntu.com/releases/24.04/
The new structure places them inside an Ubuntu-specific path:
cdimage.ubuntu.com/ubuntu/releases/24.04/
Existing release links continue to work through redirects, so normal downloads should not be affected.
Ubuntu flavours were already using a similar layout, meaning projects such as Xubuntu and other official variants require little adjustment. Their images have traditionally been stored inside their own named directories.
The main change affects daily development builds. Unlike stable release images, Canonical decided not to create redirects for older daily build URLs. As a result, previous links will no longer point to the correct location.
Daily builds for Ubuntu 26.10 are now located under a path that includes the development cycle name, while flavour builds have also adopted the updated structure.
Ubuntu monthly snapshots are not the same as traditional alpha releases. Canonical stopped producing classic alpha milestones years ago, and these snapshots are instead automatically generated checkpoints created through the distribution’s updated image-building system.
The snapshots are mainly intended as temporary testing versions. They do not receive the same level of manual quality checking as final releases, but they provide a predictable target for developers and testers who want to validate changes. They also allow Canonical engineers to test and improve the automated release process itself.
For regular users who simply want to explore Ubuntu 26.10 development, daily builds are usually a better choice because they contain newer changes and updates. Snapshot releases are more useful for people participating in testing or development work.
The next Ubuntu 26.10 snapshot is expected later in the cycle, with additional updates and user-facing features planned before the final release. Upcoming changes are expected to include early versions of the GNOME 51 desktop environment and new AI-related functionality, including voice input support that works across different text fields.
Users who decide to install Ubuntu 26.10 Snapshot 2 can continue following development by regularly applying updates as they become available. The snapshot can be downloaded from Canonical’s updated CD image server location.
