"message": "The resource operation completed with terminal provisioning state 'Failed'.",

Resource AzureJenkinsVM/downloadinitscript

Start at aka.ms/azjenkins and reproduce the deployment through the Azure portal. Inspect /var/lib/waagent/custom-script/download/0/stderr and the AzureJenkinsVM/downloadinitscript extension output, focusing on the reported shell syntax error. Done means the quickstart deployment completes without the extension failure.
