User lacks permission to complete this action. You need to have 'AddPackage'

Question

I get an error:

User XXX lacks permission to complete this action. You need to have 'AddPackage'

when trying to push a nuget package to Azure DevOps artifacts. I am the administrator This is the stage:

  - stage:
    displayName: 'Release'
    condition: succeeded()
    jobs:
      - job: 'Publish'
        displayName: 'Publish nuGet Package'
        steps:
          - download: current
            artifact: $(PIPELINE_ARTIFACT_NAME)
            displayName: 'Download pipeline artifact'
          - script: ls $(PATH_PIPELINE_ARTIFACT_NAME)
            displayName: 'Display contents of downloaded articacts path'
          - task: NuGetAuthenticate@0
            displayName: 'Authenticate in NuGet feed'
          - script: dotnet nuget push $(PATH_PIPELINE_ARTIFACT_NAME)/**/*.nupkg --source $(NUGET_FEED) --api-key $(NUGET_API_KEY)
            displayName: 'Uploads nuGet packages'

And the exact error:

error: Response status code does not indicate success: 403 (Forbidden - User '4a2eb786-540d-4690-a12b-013aec2c86e5' lacks permission to complete this action. You need to have 'AddPackage'. (DevOps Activity ID: XXXXXXX-6DF9-4A98-8A4E-42C556C6FC56)).
##[error]Bash exited with code '1'.
Finishing: Uploads nuGet packages

The git repo is in GitHub. Not sure who is considered to be the user but I don't know which other permissions to modify

Answer 1

It seems I fixed by adding to the feed's permission settings the Build Service as Contributor.

It's a bit confusing tbh but it's now working fine.
