Canonical Publishes Official Ubuntu Desktop Images for RISC-V Hardware Ahead of Ubuntu 26.10

Historically, Ubuntu has supported RISC-V hardware through official server images for years. Advanced users and hardware enthusiasts were technically capable of deploying an official Ubuntu Server image onto supported boards and manually installing graphical desktop environments—such as GNOME, Xfce, or KDE—on top of that base system using standard package managers. This approach existed well before Canonical elevated its supported hardware profile to the RVA23 specification, a strategic change implemented to concentrate software optimization on newer, more capable, and performant hardware platforms.

However, Canonical did not provide official, first-party live installation desktop media tailored for RISC-V boards.

Consequently, hardware manufacturers and original equipment vendors that brought RISC-V products to market had to bridge the gap independently. Companies collaborating with Canonical on RISC-V enablement—many of which produced and marketed RISC-V tablets, laptops, and single-board computers running Ubuntu—frequently had to compile, assemble, and host their own specialized recovery images and operating system builds. If an end user wished to reinstall the operating system, recover a non-booting device, or upgrade components, they were forced to rely on vendor-hosted downloads, third-party software repositories, or custom flashing procedures that existed entirely outside of Canonical’s primary infrastructure.

The release of Ubuntu 26.10 test builds fundamentally resolves this fragmentation. By publishing official riscv64 desktop installation media directly on Canonical’s infrastructure, RISC-V boards conforming to the RVA23 baseline are integrated directly into the distribution’s mainstream distribution pipeline. Users will now be able to download official desktop images from the exact same centralized servers that distribute ISOs for AMD64, Intel 64-bit, and 64-bit Arm architectures.

For users and organizations that prioritize long-term stability over cutting-edge development branches, Canonical is also maintaining an Ubuntu 26.04.1 LTS desktop ISO for riscv64. While the current long-term support desktop image does not yet incorporate hardware support for the SpacemiT K3, Haudiquet confirmed that support for the board is planned to land on the LTS release branch in the near future.

The newly compiled test images are currently accessible to testers, developers, and hardware enthusiasts directly via Canonical’s daily build archives. The Ubuntu 26.10 desktop RISC-V image is hosted within the standard daily-live development directory on cdimage.ubuntu.com, while the minimal Xubuntu 26.10 RISC-V image is available through the official Xubuntu daily builds repository. Both images will continue to receive updates, bug fixes, and software improvements leading up to the scheduled general availability of Ubuntu 26.10 in October 2026.
