I chose the first items in the lists, which are "English" of the
territory "Antigua and Barbuda". That's "en_AG.utf8"

When I use "en_US.utf8", the problem does not occur.

I applied this patch to my Git repo and built a new installer like this:

`./pre-inst-env guix system image -t uncompressed-iso9660 
--label="GUIX_x86_64-linux-leo" --system=x86_64-linux gnu/system/install.scm`

Then I copied the image out of the store and booted it in QEMU.

But, I still had the problem during installation. Did I miss a step?
