We normally run 'guix pull' unprivileged, so that's fine.

Guix is trying to find out your home directory, so that it can update
files in ~/.config/guix.  If your HOME environment variable was set, it
would use that, but apparently it's not set, in which case it tries to
use getpw(3) to look up the entry in /etc/passwd corresponding to your
user id.  getpw(3) failed for some reason.

It seems that you're on an unusual system, since HOME is usually set by
default.  Anyway, setting HOME should fix the issue for you.  Please let
us know if that works.

      Thanks,
        Mark
