Hi Konrad,

For some reason, it works for me with

   --ad-hoc python nss-certs guix -- \

. I’m neither sure if this is going to work on all machines (it works
when isolated with

   guix environment -C -N

, so there’s some hope), nor whether this solution is acceptable to you.
Perhaps, it’s abusing Guix. Maybe somebody more knowledgeable will
comment on this.

Bye,
