Then please use native ubuntu host to start the flash with sdkmanger first.
Virtual machine is never supported.
If you still cannot flash the board with native ubuntu host, then you still need to share both host and device side log.
Device side log means you need to buy that cable, which is actually not a expensive one.
Also, trust me that you will still need and use that cable one day if you keep working on Jetson Orin Nano…
