Push Nupkg to ProGet failing with Authentication Error

Hi there :)

I was previously running a TeamCity nuget feed which was unreliable so I am trialling ProGet.

I have successfully installed a ProGet server on a dedicated server :)

We use Teamcity to create nupkg packages and I want to integrate the Teamcity NuGet Publish Build Step to upload packages to ProGet. When I perform a NuGet publish from Teamcity, it fails with error

Now I couldn't get the suggested Name:Pass API key method to work either this fails with error too.

So, eventually I had to allow the anonymous user to have the Feeds_AddPackage privilege, which as you can imagine, is not idea.

Can you tell me how to enable NuGet publish from Teamcity to ProGet using authentication?

Product: ProGet
Version: 3.1.0

A few troubleshooting questions:

Do you have an API key specified for the feed? This would mean Admin:Admin doesn't work
Did you change the default Admin password?
Can you push if you manually run the nuget.exe command line?

Beyond that, not sure how this could happen. Is TeamCity mangling the Admin:Admin key somehow (e.g. replacing : with something?) You could verify this with a Fiddler trace.

Also, what is the actual command line value that TeamCity is running? It looks like the task is running:

NuGet.exe push C:\...\SciChart.3.1.0.4680.nupkg %%teamcity_nuget_api_key_1404377491436%% -Source  http://feed-url

which does not have the -ApiKey argument at first glance.

I am also having the same problem as the op. I have Windows Authentication enabled and the output is as follows:

Any help from one side or the other would be great. I guess I'll start working on a custom nuget / command line solution while I am waiting.

Thanks

I got the same error message, the true reason was shown in Proget Admin ui: "An error occurred processing a PUT request to http://bhmc1787.sirona.org:81/nuget/[....] already exists and the user Anonymous does not have the Feeds_OverwritePackage privilege."

Same issue here, tried with Local Users, LDAP and Windows AD, with and without API.

Did anyone managed to solve this?

Thanks!
