First, let's download an OS, I chose a basic one because I don't need lots of apps but I don't want to dive into a complex install immediately.
You'll need a micro SD card for the OS image. This is all in Linux by the way.
unxz 2023-05-03-raspios-bullseye-armhf.img.xz
to extract; we now have a 32 bit OSInstall Raspberry Pi Imager from https://www.raspberrypi.org/downloads/
sudo apt install ./imager_amd64.deb
rpi-imager &
Now to test the Pi:
sudo apt-get update
sudo apt-get upgrade
I found that if you decide to join a different WiFi network later then
you might use raspi-config
to add it but that doesn't delete your
original WiFi settings. You will have to remove the first network from
/etc/wpa_supplicant/wpa_supplicant.conf
.
