Identify the Issue:
The error message suggests that there is an issue related to a CLI template and the variable 'vm_interface_number.'
Understand that 'vm_interface_number' may not be recognized or available as a valid meta-variable.
Review Pre-defined Templates:
Check the pre-defined templates or configurations being used during the upgrade process.
Verify if the variable 'vm_interface_number' is being used within these templates.
Remove or Adjust the Template:
