These are some notes for myself when setting up arch.
before you can use the package manager
pacman you need to run:
This sets up your abilit to set some keys and then use them to check the fingerprints on packages you're going to install.
If you're on a raspberry pi, you'll need to add the keys for
archlinuxarm in particular:
pacman-key --populate archlinuxarm
Thereafter you can go about installing whatever you need.
If you need to remove all the keys you have added to start over, you can:
rm -rf /etc/pacman.d/gnupg
before running the init again.
In order to get make, and a bunch of basic tooling:
pacman -S base-devel
I always need to download some AUR packages. Usually we still need to download a client:
git clone https://aur.archlinux.org/yay.git cd yay makepkg -si
