I am trying to upgrade GuixSD, originally installed from the 0.13.0 amd64 USB image. However, the `guix pull' command exits badly.
``` root@watson ~# guix package -u substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0% substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0% The following package will be upgraded: guile-git 0.0-4.951a32c → 0.0-4.951a32c /gnu/store/cjg6sngjq540k38s5l3nfxpydybhpas0-guile-git-0.0-4.951a32c nothing to be done root@watson ~# guix pull Updating from Git repository at 'https://git.savannah.gnu.org/git/guix.git'...
