Troubleshooting NuGet

Q. I'm unable to authenticate using HTTP Basic Authentication with a password or with an entitlement token. I'm using dotnet core SDK 2.2

This is the error:

Unable to get repository signature information for source
https://nuget.cloudsmith.io/YOUR-ACCOUNT/YOUR-REPO/v3-index/repository-signatures/X.X.X/index.json
error : Response status code does not indicate success: 401 (Unauthorized)

It looks like this (not being able to use username/password directly on a source) might be an accepted bug in dotnet 2.2, possibly fixed later, as referenced in the following GitHub issues:

• https://github.com/dotnet/cli/issues/10356
• https://github.com/NuGet/Home/issues/4668

SOLUTION
Add the source using nuget sources as follows first::

nuget sources add -Name NAME -source https://nuget.cloudsmith.io/YOUR-ACCOUNT/YOUR-REPO/v3/index.json -Username YOUR-USERNAME -Password YOUR-API-KEY-OR-PASSWORD -StorePasswordInClearText

Then do dotnet restore like:

dotnet restore -s https://nuget.cloudsmith.io/YOUR-ACCOUNT/YOUR-REPO/v3/index.json --configfile ~/config/NuGet/NuGet.Config

If you want to use an Entitlement Token instead of a username and password/API-Key, use "token" for the username and an Entitlement Token as the password.
