URGENT Failed installation at "Add the official OpenVPN APT key" #1794

Expected behavior:

Pass the Add the official OpenVPN APT key step

Actual Behavior:

Fails at the step

Steps to Reproduce:

1. Create 1 core Ubuntu 16.04 machine on DigitalOcean
2. apt update && apt upgrade -y && reboot
3. ssh-keygen (the script fails when a key not found on the machine)
4. Follow the official installation steps
5. Start streisand and select 7. No customization on the configuration. No domain submitted.)
6. The script fails at Add the official OpenVPN APT key step

I've also tried against a newly generated machine through the Existing machine option. The bug is still there. Probably applies all the provisioning options.

Here is the ANSIBLE_DEBUG=True log of the failure; https://www.pastebin.com/1ba9q0DE
