Per Pangea docs: run the installer from a clean directory - a stray pangeacluster.yml interferes with installation.

Context: Problem: The Pangea private cloud installer behaves unexpectedly. A pangeacluster.yml sitting in the current directory interferes with the installation. Pre-install checklist: confirm awscli and helm are installed, run aws configure list, check cluster access with kubectl cluster-info, and make sure pangeacluster.yml is not in your working directory (remove stray yml files first).
