Jetson TX1 installation freezes at `PageAction jetpack_device_info set_info` step


The host machine is:

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:        16.04
Codename:       xenial

We have the Jetson TX1.

I am using JetPack-L4T-2.3.1-linux-x64 version of the installation program.

I leave it on the default settings, except, I disable installing OpenCV.

I follow the instructions closely, but when getting to just restart the installation and the part where it locates the IP address, I get the following and it entirely freezes:

Agent pid 14751
Identity added: /root/.ssh/id_rsa (/root/.ssh/id_rsa)
scp -F /dev/null -o PubkeyAuthentication=no -o ConnectTimeout=30 -o StrictHostKeyChecking=no /root/.ssh/ ubuntu@
 .1.5                                    100%  390     0.4KB/s   00:00

I can reproduce this freeze by running

sudo ~/tools/JetPack/_installer/PageAction jetpack_device_info set_info ubuntu ubuntu

myself directly.

I note that I can ssh into the machine, at this point, fine enough. I did notice that ssh access was intermittent (not due to any WiFi reasons).

Does anyone have any thoughts on why this is freezing, and what to do about it? Thanks!

It turns out it works when I do it over a LAN connection; just not when the Jetson is connected via WiFi. Sad times.
