I have the same problem!!
While I flash the Jetson tx2 with “JetPack-L4T-3.1-linux-x64.run” , I get the same problem.
There is something different from the install guide. My host platform os is Ubuntu16.04 in the VirtualBox virtual machine,
and the target is Jetson Tx2. In addition, I didn’t choise the full packets, but I select the all packets except the opencv2.4.13, because
I will delevop my applications with opencv3.4.0. Is it the point of the problem?
Here is the part of the flash_os_tx2.log:
