2. Steps to reproduce the issue

Build this dockerfile:
FROM nvidia/cuda:10.1-devel-ubuntu18.04
RUN apt-get update

I note that apt-get is functioning fine in a container I build and run using:
docker build .
FROM nvidia/cuda:9.1-devel-ubuntu16.04
RUN apt-get update

I have been building ubuntu images all morning without issue. Are you behind a proxy by chance? We've had users behind proxies that have had issues clear up a few hours later. The CDN can be sensitive at times.

Yes, I am behind a proxy. I will try again tomorrow. Thanks.

[dittothat]

Yes, this was a proxy issue. All is well now. Thank you.

@dittothat I encoutered this problems as well, I wonder how to solve this if I behind the proxy?
