I solved the problem.
- I found that the ubuntu linux in the Host PC did not have /dev/loop* devices installed.
I created new ones by doing the following procedure:
$ cd /etc
$ vi modules
loop max_loop=64
lp
Reboot the host machine.
- I was trying to get lan connection between the host PC and the TX2 using wireless.
I connected both node to a wired line with internet connection. The install went through no problem.
Now the NVIDIA_CUDA_EXAMPLES are there.
Thank you for your support.
