Start with the SonarQube for Azure template deployment and the configureAppVM_DSC extension error, then inspect the PowerShell DSC Main configuration and the Grani_Download step. Verify whether the referenced SonarQube 5.6.4 URI is reachable and reproduce the deployment; done means the template deploys without the VM extension provisioning failure.
