Need help with NVIDIA-docker installation

I am trying to install system requirements for using Clara Deploy SDK. I have problems in installing NVIDIA Docker using the following command:
sudo apt-get install -y nvidia-docker2

I got the following messages:
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package nvidia-docker2

Does anybody know how to fix this problem?

Thanks,
