Sorry it took me so long to answer!

Actually, Nikita answered this question on a thread on GNUnet's mailing list:

https://lists.gnu.org/archive/html/gnunet-developers/2022-04/msg00030.html

The end of the discussion is off list. The key used to
sign the package is deprecated and not to be used any more/any where.

The proper solution should come from GNUnet, but maybe, we could bypass
the key verification in Guix. Or, I could clone the repo, claim
ownership and sign a new package myself. But that doesn't look like a
good/fair solution to me! Thoughts?!
