Unable to install nuget packages

Hi,

I'm unable to install any nuget package under Rider rs-163.10479 on Ubuntu 16.04 64bits with dotnet core 1.1.0 installed. 

It's simple to reproduce the error. Just create a dotnet core console application from Rider and try to install any nuget package (automapper, newtonsoft.json, dapper.... or others). 

You'll get the following error below:
