Okay :)

This works for me on my Debian system...

Did you try following the instructions related to X.509 Certificate
setup yet?

https://www.gnu.org/software/guix/manual/html_node/Application-Setup.html#X_002e509-Certificates-1

Those error messages suggest that `guix import` can't find the X.509
certificate store, which suggests that the cert store is either not
installed or the relevant environment variables are unset or set
incorrectly.
