I got this error when installing Nuget google calendar API 3.0, in Visual studio 2012. Go to Tools -> Extension and updates -> there under updates you will find Nuget Package Manager. Try to update it. This worked for me.

It works now. I went to the site and had to uninstall and reinstall NuGet. Thanks

I've had a similar problem and going to the website linked in the error message simply redirects to https://www.nuget.org/. Trying to install NuGet from there, did not seem to work either.
I then tried to update NuGet via the other suggested approach (from Selvantharajah Roshanth)
Go to Tools -> Extension and updates -> there under updates you will find Nuget Package Manager
There was no update option available there.
I then uninstalled it, went to the Online section of the "Extensions and Updates" and searched for Nuget. Installed the Nuget Package Manager from here which installed the newest and latest version. This resolved the error.
