Ubuntu 25.10, codenamed ‘Questing Quokka,’ has reached a significant milestone with the availability of its daily builds for download. This marks the beginning of the development cycle for the next Ubuntu release, set to culminate in a stable version by October 7, 2025, although this date may change due to the nature of software development.
The first installable ISO images are now open for testing. Currently, many changes are not prominently visible, as the focus is primarily on internal updates and fixes at this early stage. However, as the months progress, users can expect new user-facing features and substantial improvements to begin appearing.
What are Ubuntu Daily Builds?
Daily builds are essentially development snapshots generated each day. They serve as a testing ground for developers and enthusiastic users who want to contribute to the testing process of the upcoming release. These builds are not recommended for everyday use due to potential bugs and the nature of partially implemented features.
That said, running a daily build provides a unique opportunity to witness the evolution of Ubuntu firsthand. Users can treat these builds like a rolling release, applying updates as they come in and observing the platform’s development.
How to Download Ubuntu 25.10 Daily Builds
Interested testers can download the daily builds from the Ubuntu CD image server. Options are available for 64-bit Intel/AMD systems, as well as ARM64 ISO files for compatible hardware. Users may create bootable media by flashing the image to a USB drive or opting for installation within a virtual machine for safety.
When selecting a build, it’s advisable to use the images in the ‘current’ folder, as they have undergone automated testing. The ‘pending’ folder may contain images that lack this validation, so proceed with caution if choosing from there. Raspberry Pi users should check back later for updates to the IMG files in the ‘daily-preinstalled’ folder.
Testing the daily builds comes with its challenges, but it plays a crucial role in enhancing the stability and functionality of the final release. Users are encouraged to report any bugs or crashes encountered during their testing experiences.
