Installing dotnet new template not working from NuGet Feed, works locally

Question

Looking for some guidance on fault finding an install from dotnet new -i <NUGET_PACKAGE_ID>

I have a template which is packaged and deployed to an Azure Devops NuGet Feed. I can't install this template when I use the dotnet new -i <NUGET_PACKAGE_ID> However I'm able to install it if I download .nupkg file from nuget server and install it from the file system.

I get no diagnostics messages from the install process. Is there a way of seeing detailed messaging on what is wrong with this template. I'm suspecting it's an auth problem or similar.

Answer 1

Is there a way of seeing detailed messaging on what is wrong with this template.

You can add add the DOTNET_CLI_CONTEXT_VERBOSE environment variable with value true to get more verbose logging.

Then you will get the actual error, which is most likely an authorization issue:

Response status code does not indicate success: 401 (Unauthorized).

In that case you need to install the Azure Artifacts Credential Provider and run the install command interactively once again:

dotnet new -i <NUGET_PACKAGE_ID> --interactive

Then you will get instructions on how to authenticate with the Azure Devops NuGet feed.
