The issue is that we are unable to install/upgrade jetpack2 on our jetson tx2s from a Ubuntu 18.04 host. If you install python 2.7 there are still issues with 1) flashing the tx2 in recovery mode and 2) post flashing installing the sdk components via the USB network.
We need clearer instructions from nvidia on how to make sure our Ubuntu 18.04.2 hosts are configured properly (besides lsusb and check fro nvidia and change the USB cable).
I notice you also meet error even when using flash.sh script to flash tx2. Is that correct?
According to your comments, I believe you already put the device into recovery mode (rcm) and you could see there is one “NVIDIA Corp” device in your “lsusb” list, right?
