NuGet Packages for Visual Studio 2012 will not Restore in MonoDevelop 5.0.1

Question

I'm relatively new to managing packages using NuGet. I used Visual Studio 2008-2010 for a couple of years, and used NuGet a little, but I'm far from an expert.

I have a Visual Studio 2012 program that I did not write and I'm trying to get the program to compile under MonoDevelop 5.0.1. When I load the project into MonoDevelop, the Package Console reads:

WARNING: Error: SendFailure (Error writing headers)
WARNING: Error: SendFailure (Error writing headers)
WARNING: Error: SendFailure (Error writing headers)

The application was terminated by a signal: SIGHUP

I've tried using the package manager to re-add these packages to the project, then remove the ones MonoDevelop cannot find, but I cannot get the project to recognize the packages. I've seen and read several threads on the topic some mentioning an xbuild feature that I cannot find anywhere, but those threads don't clearly address the problem, and I've found none that provide a comprehensive solution.

If there's anyone who has a comprehensive solution to this problem, please post it. I'm sure a comprehensive solution would be very helpful to a lot of people trying to convert Visual Studio projects to MonoDevelop.

Answer 1

Try running the following:

mozroots --import --sync

That should fix the SendFailure error.
