I have downloaded Jetpack latest version from Nvidia website to install it on my TX2.

here is my setup:
My PC is connected to Internet via LAN connection.
TX2 is connected to the PC via LAN connection using Network card.

After installing Ubuntu, Jetpack fails due to a permission denied error.

I think you must install ssh then config it first!
Your log showed the problem came from ssh. You may try connect ssh to tegra device 10.0.0.2 using username and password: “ubuntu” or “nvidia” (username is same as password)

TX2 is connected to the PC via LAN connection using Network card.
->> I am not sure what does this mean, could you share more detail? Does your tx2 connect to host pc or connect to a router?

mkdir: cannot create directory ‘/.ssh’: Permission denied
-> It looks like the owner of your device is wrong. Could you share below info to use?
