Hello.

I installed wireguard, but I could not find the /etc/wireguard
directory. I thought it could be good to update guix. I did guix pull.
It took a long while until it finished. At the end it showed the
following lines:


./guix/serialization.scm:80:6: In procedure read-int:
ERROR:
  1. &nar-error:
      file: #f
      port: #<input-output: file 10>
guix pull: error: You found a bug: the program
