I am a novice but can follow directions. What else can I provide? Following this guide: https://help.gnome.org/users/gnome-user-share/stable/gnome-user-share.html
The Personal File Sharing GUI does not exist: Failed to execute child process "/usr/bin/gnome-file-share-properties" (No such file or directory) I forced a downgrade to gnome-user-share from stable. It complained about dependencies obviously and will not start, but the configuration GUI is accessible.
