Ubuntu 26.10 RISC-V Desktop Images: How to Try Them Now

Ubuntu 26.10 RISC-V desktop images are now available to download and test, and that is a first for the distribution. In a post on the Ubuntu Discourse on October 9, 2026, Canonical developer vhaudiquet announced that Ubuntu 26.10, codenamed Stonking Stingray, "brings desktop images to RISC-V." The final release is due on October 15, and the SpacemiT K3 Pico-ITX board moves into the officially supported list alongside it.

• What is new: riscv64 builds of Ubuntu Desktop for 26.10, downloadable today as experimental daily images.
• Release date: Ubuntu 26.10 ships on October 15.
• Supported hardware: the SpacemiT K3 Pico-ITX gains official support with this release.
• No board needed: an XFCE-based Xubuntu Minimal image runs under QEMU on a host with Ubuntu 25.10 or later.

What Did Canonical Announce for RISC-V?

Until now, Ubuntu on RISC-V has meant server and preinstalled board images. With 26.10 there is a live desktop ISO for riscv64, the same kind of installer image that x86 and Arm users are used to. Ubuntu Desktop on RISC-V uses GNOME, as it does everywhere else.

Getting there took real engineering. The installer's interface is built with Flutter, so the team needed a riscv64 build of Flutter 3.44.0; according to the post, Canonical pushed the RISC-V support upstream, where it is still in review. On the hardware side, the kernel team cherry-picked a series of patches for the SpacemiT K3, many of them for display support, so that a graphical desktop works on the board at all.

The result is that the K3 Pico-ITX's documentation page moves from the community supported section to the Ubuntu supported boards section. If you followed our earlier look at the SpacemiT K3 Pico-ITX as a RISC-V desktop, this is the mainstream distribution support that board was waiting for.

How Can You Try the RISC-V Desktop Today?

There are two routes, and one of them needs no RISC-V hardware.

• On a SpacemiT K3 Pico-ITX: download the daily stonking-desktop-riscv64 ISO from Ubuntu's cdimage server and follow the K3 install guide in the Ubuntu hardware docs.
• In emulation: use the Xubuntu Minimal riscv64 image with the ready-made QEMU command line from the same docs.

The emulation route comes with two practical notes from the announcement. First, emulating the RVA23 profile requires a recent QEMU, which in practice means a host running Ubuntu 25.10 or later. Second, pick the right image. The post warns that "the GNOME desktop can take 30+ minutes to load under QEMU," which is why the lighter XFCE-based Xubuntu Minimal image is offered. That image is unofficial and unsupported, and is there mainly for virtual machines.

What Is Still Experimental?

Canonical is clear that these are test images. They are labeled experimental, with known issues the teams are working through before release day. Early builds may be missing the App Center, the Prompting Client and other desktop snaps that are still being bootstrapped for RISC-V. Ubuntu 26.04 LTS does not gain official K3 support; this arrives with 26.10.

The announcement also does not make claims about graphics acceleration, so I would treat desktop performance on real hardware as something to measure once the final image lands.

Why This Matters for Small Computers

A new CPU architecture becomes practical when ordinary software shows up for it. An official Ubuntu desktop image gives RISC-V boards the same starting point that made Arm boards approachable: one familiar installer, a familiar desktop and a standard package archive. For anyone weighing a RISC-V board against the options in our Raspberry Pi Desktop for PC and Mac guide, the software gap just narrowed.

It is a milestone worth marking, and I will be watching how the final image runs on October 15. More in our mini computer coverage.
