Canonical is pursuing a rather ambitious baseline of Ubuntu 25.10 RISC-V too require the RVA23 profile that will leave most existing RISC-V developer boards to using Ubuntu 24.04 LTS or Ubuntu 25.04. They continue to pursue this RISC-V baseline and with more of the necessary alterations for it being prepped for landing into the Ubuntu 25.10 archive.
