Any ideas ?

I'm getting this error too.

It is occurring on an On-Premises DevOps Services Agent.

@JeroenDaniels Let me know if you find a work around

from powerapps-samples.

@scberr

It is working on our agents now, i tried a lot of things so i'm sorry but i can not tell you specifically what solved it. It had something to do with NuGet on the machine.
So first install it manually on the Agent.

Secondly i added this YAML step at the beginning of the pipeline to unregister the packageSource:

• task: PowerShell@2
  inputs:
  targetType: 'inline'
  script: 'Unregister-PackageSource -name nuget.org'
  errorActionPreference: 'continue'

I hope this helps you.
