For some reason I have to delete some packages to install others... Both related an unrelated to this guide.
Trying to install packages from step 3C gives an error and can't get this dependency: libelf1. And if I install that package alone, it removes many others, including some from step 2B. Then, if I install again the packages from 2B, it will remove a few from 3C.
I'm using Armbian Bookworm Minimal on my Orange Pi 5 Pro, with just a handful of extra packages (including gnome-session, gnome-terminal and firefox-esr).
