How to remove keys from Hockeypuck OpenPGP key server

• First find the Hockeypuck hash of the key(s) to be removed via the web search of your key server instance;
• On the index, copy the hash value (Hash=HASHVALUE) (it's the hex representation of MD5);
• Connect to the PostgreSQL interface of your Hockeypuck server;
  • psql hkp
  • Find the corresponding keys from their hash value;
  • select rfingerprint from keys where md5 in ('HASHVALUE');
  • This will return the corresponding fingerprints;
• Then delete the associated sub-keys;

Raspberry Pi OS on KVM

NOTICE

This steps and links provided in this gist are significantly outdated (having been created in 2020) and should not be followed. I will look into updating them when time permits.

Introduction

Raspberry Pi OS is a Debian Linux derivative for the Raspberry Pi. "KVM" is a native open source virtual machine management service for Linux workstations and servers that leverages QEMU and libvirt. There are a variety of recipes for getting Raspberry Pi OS guest virtual machine up and running on KVM. Having tried many of these, this is the one I now use. Tested on Ubuntu 18.04 LTS Desktop, with all that implies (YMMV).

This is a "just for fun" project that I don't expect to make serious use of. With several actual Pi boards around the workshop, being able to reliably run on an emulator isn't really a major need.
