I have the Guix package manager installed on Trisquel 9 (Ubuntu 18.04 based) and whenever I do "guix pull", "guix package -u", etc. As a first response, I see the following warning -- "guile: warning: failed to install locale".

I have installed the glibc locales package already. How do I resolve this? I suspect this is related to why some programs like "peek" (a GIF recording app) show me broken UI characters.
