@chicagobob123 Looks like the NCSDK install is failing during the sudo apt-get update part of the NCSDK install. Likely you have some packages with broken/outdated links. Try changing the update server to the main server (go to System Settings, then Software and Updates, then in the drop down menu for Download from: choose main server). Afterwards try sudo apt-get update again.

You can also try a fresh install if it is an option.
