I’m running 5.13 on RPi 2 and I think it’s time to finally update, I only use it for lightbulbs and motion sensors really and it’s running fine aparto from not being able to make a backup and update via the GUI. I think it’s best to just make a fresh install, I’m going through the setup and I can only choose Home Assistant OS 10.3 (RPi 3) - can I choose this to install on my RPi 2?

Update: I think I found a proper release for RPi 2 here: https://github.com/home-assistant/operating-system/releases haos_rpi2-10.4.img.xz

Do I just install it using RPi Imager and then selecting custom img?
