See the last message: "certificate could not be verified".

You need to install certificates first and setup some environment
variables.

That is described here:

https://www.gnu.org/software/guix/manual/en/guix.html#X_002e509-Certificates

Can you get over that problem then?

Unfortunately, I'm getting then to another error:

guix import cran --archive=bioconductor tracklayer

Currently, I don't have time to track that down further.

Either you don't have that second problem, someone else has a solution,
or I will come back to this back later.
