QubesOS is amazing for security, and equally amazing at making CTFs 10x harder than they need to be. It’s the firewall’s fault.

When you try to run FreeRDP 3, you will likely get the BadAtom error. This error is vague, and as usual, there’s zero documentation about it that actually helps. Here’s the post I wish existed when I needed it.

Nix is great for keeping your system clean and your sanity slightly intact. But thanks to how QubesOS handles templates and persistence, it’s not quite plug-and-play.

After this guide, you will be able to:

• replace apt or pacman with the nixpkgs package repository, even if you don’t care about declarativity
• use home-manager to set up all your configs and apps declaratively with just one config file and use it on any machine
• use any nixpkgs package one time only and without bloat, fix dependency hell and weird dependencies
