I am an engineer with many years Linux experience but am finding the installation of the Jetpack 6 on my new Jetson Orin Nano Deveper Kit extremely time consuming and frustrating. I cannot even find the tags for “installation” or “setup” in the boxes above.
My first problem is that my OS is Ubuntu 25.10 and SDK packs are only available for 25.04 so without changing my complete OS the SDK route is not available to me.
I have managed to setup a working system on the SD card with the NVMe unmounted but I would like to use the NVMe =as the primary root filesystem and use the SD card for other partitions and directories. But I can fin no way to flash the NVMe with the SD card data. I think I made an error at the start and downloaded the Jetson AGX Thor Developer Kit, by mistake. When I booted this I was asked if I wanted to flash it to the NVMe which I did. So now my NVMe has a wrong version installed under a user called Jetson for whom I have no password. What I would like to do is re-flash the NVMe with the working Jetpack 6.2.1 fir the Orin Nano but I have learned that starting with JetPack 6.x, NVIDIA removed the old nvme-install.sh helper from the SD-card images. Great!
Any help would be really appreciated, even where to post this queriy correctly would be useful ;-)
