Ubuntu – 16.10 Nautilus options missing from menu

The extension for this menu entry is in the package deja-dup.

% apt-file search /usr/lib/nautilus/extensions-3.0/libdeja-dup.so
deja-dup: /usr/lib/nautilus/extensions-3.0/libdeja-dup.so

Therefore and as you don't use backups (really? You should read this.), a simple solution. Remove Déjà Dup from your system:

sudo apt-get remove deja-dup

and the menu entry will disappear.

Unfortunately this solution is like you having cancer and not wanting to take any chemo-therapy because it makes you feel bad. The better solution is to actually do backups, because otherwise we'll see each other again in a few years when your hard drive blows up and you've lost all your data!

gtk-menu-images and gtk-button-images have been deprecated and maybe are being ignored.

This link may be of help to you. And I transcribe the post contents here:

(I've already posted in http://forums.fedoraforum.org/showthread.php?p=1680581#post1680581 , re-posting here for users not subscribed there):

Both gtk-menu-image and gtk-button-images were deprecated and ignored, after that they made them deprecated but not ignored: https://git.gnome.org/browse/gtk+/commit/?id=627a03683f5f41efbfc86cc0f10e1b7c11e9bb25 https://git.gnome.org/browse/gtk+/commit/?id=c46aca463a9d66cf402ec8c3f9f2e2efc98c42ca

the problem is the gsettings keys (org.gnome.desktop.interface buttons-have-icons and menus-have-icons) are gone so I don't see a way to set them...

However it seems you can set the relevant GtkSettings via the gnome-settings-daemon xsettings plguin: open dconf-editor -> org.gnome.settings-daemon.plugins.xsettings and change the overrides key from:

{} to:

{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>} usually the change is instantaneous (e.g. in gimp), but some apps need to be restarted (e.g. firefox).

Or just use gsettings:

gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1>}" but note that this method overwrites the current value of that key; one obvious caveat is if you've previously enabled pasting with the middle click from gnome-tweak-tool -> "keyboard and mouse", you'll need to re-set it there again (unlike the above gsettings command, gnome-tweak-tool "adds" new values to the overrides key and doesn't blindly overwrite it).

Edit: testing recently, it seems now that toggling either of these settings in gnome-tweak-tool remove the custom values added above:

Top Bar -> "show application menu" Keyboard and mouse -> middle-click paste so if you toggle any of those settings you'll have to re-add the 'Gtk/ButtonImages': <1>, 'Gtk/MenuImages': <1> bits.
