Canonical ships official Ubuntu desktop images for RISC-V

Canonical is now building official riscv64 desktop images for Ubuntu 26.10, with experimental GNOME and Xubuntu ISOs for SpacemiT K3 boards. The builds are unsupported for now, snaps like App Center aren't RISC-V ready, and the final release is set for October 15, 2026.

• Experimental Ubuntu 26.10 builds target SpacemiT K3 RISC-V boards
• GNOME boot in emulators can take up to 30 minutes; Xubuntu is lighter
• Canonical added RISC-V support to the Flutter library
• Final Ubuntu 26.10 release is scheduled for October 15, 2026
