Some people (me) would prefer the straight GNOME experience as opposed to the Unity style desktop offered in Ubuntu 17.10.
How can I get the standard GNOME desktop and interface?

There are two methods to easily gain a more GNOME like experience in Ubuntu 17.10.
The first method is to run the program
sudo apt install gnome-session
This will undo many of the features that have been added to GNOME, such as the always-on dock, but will leave the Ubuntu color scheme.
The second method is to execute the command
sudo apt install vanilla-gnome-desktop
This will install the GNOME themes as expected from prior versions of Ubuntu GNOME, change the Plymouth splash screens, and install several common GNOME utilities.
If you want full GNOME, you can install it by using:
sudo apt install gnome
This package installs around 293 packages/utilities and on the other hand
vanilla-gnome-desktop package installs around 170 packages/utilities which in my opinion aren't required just to experience Vanilla GNOME. You can install a 'minimal' version of vanilla GNOME which need only 4 new packages using:
sudo apt install ubuntu-gnome-desktop
It doesn't include additional packages (which many of times are useless) and GNOME plymouth but you can experience vanilla GNOME without using much space.
