Release file has an invalid format

[marker68]

I have used the *.deb file from https://developer.nvidia.com/cuda-downloads and got the following error:

The message is in Japanese, but actually it say that the Release file which is downloaded from your repo server has an invalid format (it doesn't have the Date entry).
I had a look on the file http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1504/x86_64/Release

Hello,

You are trying to use the Ubuntu 15.04 repository with Ubuntu 16.04. Also, 16.04 is not officially supported right now. Therefore I don't believe this is a bug.
