The default mirror for /etc/pacman.d/endeavouros-mirrorlist was basically dead when I was trying to install last night. I ran the suggested mirror ranking program ( eos-rankimirrors ) in the live session thinking it would be carried over during install to the chroot, but it wasn’t. This caused pacman to hang whenever it was trying to pull the main chunk of packages. (Base / Gnome / Printing). I think from the EOS mirrors it needed just 4 packaged but manually doing the pacman commands inside the chroot showed speeds around 5-15KiB/s or timeouts when pulling those files.
I manually copied the /etc/pacman.d/endeavouros-mirrorlist (post eos-rankimirrors) into the /tmp/calamares-root-whatever/etc/pacman.d as soon as it was created and this time the install finished.
FWIW, I’m East Coast USA.
