This gist will show how to setup a generic SBC Debian / Ubuntu install as a headless Bluetooth A2DP audio sink. This will allow your phone, laptop or other Bluetooth device to play audio wirelessly through a Rasperry Pi.
This is forked from another gist specific to the Raspberry Pi on Stretch. A required package isn't in Ubuntu's repos, so in this gist we build it from scratch.
Tested to be working on Armbian/Ubuntu/Debian images of the Orange Pi Zero, ODROID XU4, ODROID N2, and Atomic Pi.
This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.

In this scenario we are going to set up Vault to sign SSH keys using an internal CA. We will configure the SSH secrets engine and create a CA within Vault. We will then configure an SSH server to trust the CA key we just created. Finally we will attempt to SSH using a private key, and a public key signed by Vault SSH CA.
