Context:

Using guix as a package manager under a foreign up to date 
archlinux distribution.

The output of guix describe --format=channels is

    https://gitlab.com/csantosb/wikidata/-/blob/master/guix-profiles-backup/guix-channels.scm

Problem:

When using duplicity to backup to a sftp server, I get this error 
message

    BackendException: Could not initialize backend: No module 
    named 'paramiko'

I have installed python-paramiko, but this doesn't fixes the 
problem.
