Prior to updating to 2.7, nuget.exe seemed to respect the package sources defined in nuget.targets, located in the same directory as nuget.exe. After upgrading, nuget is unable to restore a package from an additional source. I tried adding the source to nuget.config as well, but that didn't help. I'm able to list the packages from that external source, which is interesting.
I tried updating the nuget server to the latest 2.7 build and that did not fix the issue.
