I am trying to update using sudo apt-get update on my Jetson Tegra TX1 but I am getting the following error..

E: GPG error: http://ports.ubuntu.com trusty InRelease: Clearsigned file isn't valid, got 'NODATA' (does the network require authentication?)

Tried different things but it didnt help.

Make sure you have internet connection. Try to use

wget http://ports.ubuntu.com/ubuntu-ports/

and see what you'll get
