This reminds me an issue I had running qemu-binfmt based builds on a
foreign distribution. From what I understand you are offloading builds
to a Guix System machine, but is the machine displaying the above
message also running Guix System?

If that's not the case, there are some tricks to make it run, that I'm
supposed to document, see:
https://lists.gnu.org/archive/html/guix-devel/2019-11/msg00423.html.

Thanks,

Mathieu
