After installing GuixSD 1.1.0 into a VirtualBox VM and following the After System Installation steps (https://guix.gnu.org/manual/en/html_node/After-System-Installation.html#After-System-Installation), the update fails when trying to update nss-certs.

Possibly related to  #37662

The error is always when installing nss-certs, is entirely repeatable, and therefore not to do with a network connection.

I tried this about 4 months previous, and again today, and have been presented with exactly the same error.

The error always occurs at 48.3%.

A post on Reddit (https://www.reddit.com/r/GUIX/comments/hxrmzn/guix_system_error/) has the exact same error as this. The error even occurred at the same 48.3%!

I selected the Australian Locale (en_AU) during this installation. I am unsure why the locales error is present after installation. I ran the commands it suggested last time and the warning did not disappear, nor did the nss-certs error get resolved.

I can run --fallback, but to me this is ignoring an obvious issue with a vanilla system that should work out of the box.

Steps to reproduce:

* Create new VBox VM
  *   Install GuixSD Graphical
  *   Select Australia locale
  *   Select defaults
  *   boot into the system
  *  $ guix pull
  *  $ sudo guix system reconfigure /etc/config.scm
