Disclaimer: I'm not sure how things go on Guix (without the final SD) and I
haven't been using Guix for some time now so I don't remember well

In GuixSD (please notice the final SD) the user profile and the root
profile are distinct
I don't remember if they are distinct in Guix too

But when I used GuixSD I experienced this fact: Guile libraries installed
in your user profile were not accessible to the Guix root profile Guile. I
had to install Guile in my user profile along with some Guile based
packages.

If you installed Gnutls in your user profile (that is, if you installed
gnutls with the line: "guix package -i gnutls" as a normal user) then the
Guile in the Guix root profile may be not able to acces your gnutls
installation

So, I guess Swedebugia means installing Guile through Guix, along with
Gnutls

Like this:

guix package -i guile

If you don't do this, it's possible that you are using the Guile provided
by Ubuntu

Or that you are using the Guile provided by the Guix root profile (again: I
don't remember if this distinction applies to Guix too)

In fact I'm inclined to think this is what is happening because you
reported that you are using Guile 2.2.4 but I'm pretty sure that the Guile
in Ubuntu is Guile 2.2.3.
I know because I am using that one, I haven't got Guix on my machine

Was that helpful ?

I haven't been using Guix for a while now so I'll pass on this one

But please consider asking these questions on the guix-help mailing list !
