Hi! I'm having an exception when trying to install nss-certs. I have glibc-utf8-locales installed, and even tried installing glibc-locales even though my LANG=en_US.UTF-8.
I'm running Guix the package manager on top of Void Linux.
I want to install nss-certs because curl, youtube-dl, and probably others all complain about failure to verify certificates. I'm mentioning this because it might be another bug altogether.

$ guix install nss-certs
The following package will be installed:
nss-certs 3.59

PS: Great job on Guix!! With so many similar package managers out there, it was about time someone actually invented something new!
