How can i upgrade my jetson orin to jetpack 6

THIS FAILED AS THE USB CONNECTION DROPPING EACH TIME MAKES IT GO IN CIRCLES. ONLY OPTION LEFT IS TO HAVE UBUNTU ON A USB STICK AND TAKE IT FROM THERE
Using Ubuntu on stick
I used the LTS version 22.04 for that.
Download the ISO
Follow these instructions https://ubuntu.com/tutorials/create-a-usb-stick-on-windows#9-installation-complete
Also that does not work because of size limitations,. ... sigh, so you do need a fully installed Ubuntu for this, which I don't have.
So I ended up installing Ubuntu on the old test PC and did the update from there. Also that was not 100% successful, I had to do the Jetpack afterwards, but at least I got the Jetson to 22.04 LTS.
