LightDM broke, can't reinstall it as I can't connect to internet. Can't chroot either

In chroot, try the following to see if the keys will get reset:

mv /etc/pacman.d/gnupg /etc/pacman.d/gnupg.old
pacman-key --init
pacman-key --populate archlinux endeavouros
pacman -Syy archlinux-keyring endeavouros-keyring
pacman -Su
