[arch-general] how to upgrade 2017 server ?

i have a server that has not been booted since 2017, i tried upgrading with pacman -Syu, i have post the screen output at http://paste.openstack.org/show/788264/ i thought adding Eli Schwartz' personal repository to pacman.conf would have allowed the upgrade with his Binary builds of pacman-static. is my problem still to do with the xz to zstd change or something different ? shadrock
