Looks a lot like you tried to install into an already existing installation without reformatting the partition. Same with your snipped: pacstrap: :: installing systemd (259.5-1) breaks dependency ‘systemd=259.3’ required by systemd-resolvconf says there is already an older version installed, indicates the same installing in unclean target partition.
