Ethernet connection missing after Cuda installation failure with Jetpack
Ubuntu 16.04LTS, Jetson TX2, Jetpack 3.
Computer and Jetson connected to a hub, connected to internet.
After downloading Jetpack 3, I tried to flash the Jetson and install Cuda 8.
I tried to install using two different computers (wifi turned off).
I wasn't able to install Cuda, I had an error.
For both computers, after the failure during the installation, the Ethernet connection doesn't work anymore.
I checked and compared with another computer the /etc/network/interfaces and /etc/NetworkManager/NetworkManager.conf files.
I hope that someone could help me.
I tried these commands to figure out what was wrong.
Code:
