As you may already know, the Ubuntu Gnome distribution is terminated.
It is now replaced by Ubuntu himself that is now using Gnome-Shell as desktop.
The main drawback of Ubuntu is that it does not allow to install Gnome Extensions and comes with many specializations done by Canonical.

With the latest 17.10 version of Ubuntu that have been released yesterday it is not straightforward to figure out how to get a replacement of the Ubuntu Gnome distribution.
Here is how you can proceed to get a vanilla Gnome like it was available in Ubuntu Gnome 17.04.

Once Ubuntu 17.10 is installed you get the following screens

Install the ‘vanilla-gnome-desktop’ package by typing in a console

$ sudo apt install vanilla-gnome-desktop

After reboot you get the following screens

Ubuntu Gnome is back ;=)

You can also get more Gnome applications

Just install the ‘gnome’ package

$ sudo apt install gnome

/Enjoy ^_^
