GSettings schema compilation fails:

$ LC_ALL=C glib-compile-schemas /usr/share/glib-2.0/schemas/
/usr/share/glib-2.0/schemas/org.gnome.settings-daemon.plugins.sharing.gschema.xml:17:1  Error on line 17 char 1: <schema id='org.gnome.settings-daemon.plugins.sharing.service'> already specified.  This entire file has been ignored.

That is due to /usr/share/glib-2.0/schemas/org.cinnamon.settings-daemon.plugins.sharing.gschema.xml file from cinnamon-settings-daemon-3.4.1-1.fc25.x86_64 package that has duplicated schema with id="org.gnome.settings-daemon.plugins.sharing.service".

This in turn causes gnome-settings-daemon to skip 'sharing plugin' when loading modules:

And then you cannot enable file sharing via GUI from gnome-control-center (the toggle remains off):
