Ubuntu 23.04 host OS, Ubuntu's native Deja-Dup and Duplicity were removed prior to installing from guix.
When I installed Deja-Dup, it required duplicity to be installed. I installed it, and it still wasn't found. Deja-Dup requested and I granted permission to install duplicity on its own. Any idea what's going on with that? Deja-Dup definition for your convenience. https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/gnome.scm#n1815
