Apple Borked my Nix!

Ok, so you've had nix (home-manager) working fine. Then Apple tells you it's time to update.

Ok. Reboot. Oops. It has now broken your Nix setup. Here's some stuff to work through. YMMV.

Note: This is what worked for me, who was just using nix + home-manager. The upgrade that I last did that caused all these issues was 12.3.X > 12.4

How to Install Nginx, MariaDB, PHP-FPM on Ubuntu 20.04

This is a way to install and set up Nginx, MariaDB and PHP-FPM on Ubuntu 20.04.

NOTE: This has been prepared for ease of use in mind, not security, mostly in development machine. Please do not use these instructions to setup on a public server environment. Use other proper manuals instead.

First fetch the latest package list of Ubuntu:

$ sudo apt update

NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

Simpler stack / less moving parts
Works directly with ssh, ssh-add and ssh-keygen on most computers
Simpler
Private key can never leave the FIDO device
