Missing repositories in jetson-nano image

[vectorcrumb]

Hi, I think there's an issue with the jetson-nano example. Line 34 references the /etc/apt/sources.list.d/nvidia.list file which doesn't exist. I believe this line is missing from the Dockerfile:

RUN echo "deb https://repo.download.nvidia.com/jetson/common r32.7 main" >>  /etc/apt/sources.list.d/nvidia.list \
	&& echo "deb https://repo.download.nvidia.com/jetson/t186 r32.7 main" >>  /etc/apt/sources.list.d/nvidia.list \
	&& apt-key adv --fetch-key http://repo.download.nvidia.com/jetson/jetson-ota-public.asc \
	&& mkdir -p /opt/nvidia/l4t-packages/ && touch /opt/nvidia/l4t-packages/.nv-l4t-disable-boot-fw-update-in-preinstall
