I am having this same issue - We know that Microsoft removed Ubuntu 16 (github actions did too). I just don't know what the Queue label would be. Anyone have an idea?

I am using Azure Pipelines

I am too - I was just noting that most CI that are cloud based removed Ubuntu 1604 due to security issues.
So here is what I did to fix it for me:
in the azure-pipelines.yml comment out and add the variables for vmImageName

# queue:
#   name: Host Ubuntu 1604
variables:
  vmImageName: 'ubuntu-latest'

hope this helps...
