### Repro steps (*if necessary, delete otherwise*)
1. Select template
2. Click Deploy to Azure
3. Fill-in requested parameter
4. Deploy
5. Issue is reproduced

Start with the 101-Telegraf-InfluxDB-Grafana template and its scripts/Configfiles.zip, focusing on the tigInit Ansible step and the Python 2.7 dependency installation shown in the error. Reproduce the deployment and inspect the missing Python.h failure; done means tigVM/tigInit provisions successfully and the template deployment completes.
