NuGet 1.6 and downloading packages

I just setup a NuGet Server feed and am trying to get it working with octopus. The NuGet.Server version I setup is version 1.6 and it seems octopus is using version 1.5 from NuGet.Core.dll.

I’m not sure if it has to do with versions of nuget, but thats what I’m assuming at this point. Here’s the exception I’m getting on some packages:

The version of octopus I am using is Octopus 0.9.568.2630 (beta)

Any ideas?

Hi Sean,

Are you still running that older Octopus release, and if so, is the same issue still happening? (Sorry for the late reply).

There was a bug in NuGet’s hash verification code, I submitted a patch to them last year which I believe they incorporated in the latest NuGet.Server.

Paul,

I upgraded to the latest octopus server and nuget 1.6 and it fixed all the problems. I have it working with the teamcity nuget server that is baked into teamcity 7.0

Thanks!
