Comment 14 for bug 1586657

According to the announcement at https://launchpad.net/~gnome3-team/+archive/ubuntu/gnome3-staging/
the GNOME3 Staging PPA is no longer supported for Ubuntu 16.04 LTS. If you have the PPA enabled on that release, please ppa-purge. Then you can optionally remain on 16.04 LTS or upgrade to a newer Ubuntu version if you want newer GNOME versions.

Ubuntu GNOME itself does not have this bug.

For the remaining issue of GNOME touchpad settings not working correctly when xserver-xorg-input-synaptics is installed on Ubuntu GNOME 16.10+, see https://launchpad.net/bugs/1686081 Due to the nature of that bug, I don't think it will be possible to fix that in current Ubuntu stable releases.
