2021/09/15追記  
おそらくこのエラーだと考えられます。  
<https://github.com/NVIDIA/nvidia-docker/issues/1296#issuecomment-646521766>  
プロキシ環境下で行っているので、上記エラーが発生しているのではないかと考えております。  
docker内で  
$curl -k -L <https://nvidia.github.io/nvidia-docker/gpgkey> | sudo -E apt-key
add -  
を実行すると以下のエラーがでて実行できませんでした。

```

    $curl -k -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo -E apt-key add -
