Unable to sudo apt-get update in Docker container

pytorch/pytorch: 1.5-cuda 10.1-cudnn7-develCreate a Docker container based on the image
When I ran sudo apt-get update, I encountered the following error:

The reason seems to be the inability to access developer.download.nvidia.com.
I couldn't figure out how to deal with it, so I decided to consult with you.

The host environment is Ubuntu 18.04.3 LTS.

I look forward to your kind cooperation.

Now that I've solved myself, I'll leave a self-answer just in case.

I couldn't sudo it with a user other than root, but as shown below
I was able to update apt-get by re-entering the container as the root user.

$docker exec-it-u root<container ID>bash
root@<container name>:/$apt-get update
