I\'m trying to run NuGet on Linux (Ubuntu 12). I have Mono 3.0.6 (compiled from source).
$ mono --runtime=v4.0.303
I was able to get this working by importing the certificates into the machine store and not the user store, which is the default:
$ sudo mozroots --import --machine --sync
$ sudo certmgr -ssl -m https://go.microsoft.com
$ sudo certmgr -ssl -m https://nugetgallery.blob.core.windows.net
$ sudo certmgr -ssl -m https://nuget.org
I verified that before I did this — even after having done the original user store-based commands — the tlstest.exe tool failed, and after importing into the machine store it succeeded.
And, most important to me of course, nuget started working then too. :)
