Overview of the Issue

When Packer is generating a keypair to use the Ansible provisioner, the generated public key file is empty. This results in a libcrypto failure.

Reproduction Steps

This repository is here to reproduce the issue: https://github.com/Wenzel/bug_report/tree/packer/ansible/libcrypto_error

git clone https://github.com/Wenzel/bug_report -b 'packer/ansible/libcrypto_error'

and then

make build

Packer version

Packer v1.9.4
