built-in camera not connected--new gazp5

Not seeing an immediate way to test the built-in camera on my just-received gazelle gazp5, I installed Camorama. When opened, Camorama says the camera is not connected. I try running the system76 driver installer but keep getting an error message saying I am not connected to the internet when I do have an active connection (I tried this on both wireless and ethernet connections). Advice?
