I’m guessing the machine had remnants of a previous Guix installation,
no? See:
;; In 0.15.0+ we'd create ~/.config/guix/current-[0-9]*-link symlinks. Move

(unless (string=? %profile-directory
(dirname (canonicalize-profile %user-profile-directory)))
(migrate-generations %user-profile-directory %profile-directory))
