upgrading on GuixSD before 0.16 to 0.16 fails

[ng0@n0.is]

Hi,

I'm currently trying to upgrade out (gnunet) server to a new
version of GuixSD. Upgrading it was put off for a while due to research
reasons.

This installation is from November '18, and I'm getting stuck on a
backtrace when I'm trying to pull from the commit 0.16 tags or
anything after it.

Here's the backtrace. If it helps I can attach the config.

root@firefly ~/gnunet-maintenance/gnunet# guix system build config.scm
guile: warning: failed to install locale
hint: Consider installing the `glibc-utf8-locales' or `glibc-locales' package and
defining `GUIX_LOCPATH', along these lines:

     guix package -i glibc-utf8-locales
     export GUIX_LOCPATH="$HOME/.guix-profile/lib/locale"

See the "Application Setup" section in the manual, for more info.
