I checked my workstation, it only has public_key.pkcs7.pem

nxia@nxia:~/chromiumos/chromeos-admin/puppet/keys$ ls
public_key.pkcs7.pem

pprabhu@, did I miss any steps ?

Posted https://chrome-internal-review.googlesource.com/#/c/chromeos/chromeos-admin/+/551686 to improve the error message in #3.

FYI, #2 is also a KI: issue 796735

The provision was stuck at deploy_puppet, going to reboot the server and re-run the provision
