    Do you really want to do that? Unity is old, outdated, unsupported. GNOME is the modern, current, and supported DE. It almost 99% looks/acts like Unity, with its dock, etc. – heynnema Oct 21 '18 at 16:09

According to search results from packages.ubuntu.com you need to install ubuntu-unity-desktop meta-package ("The Ubuntu Unity desktop system"):

sudo apt install ubuntu-unity-desktop

Then reconfigure LightDM as main greeter when prompted or manually with

sudo apt install lightdm
sudo dpkg-reconfigure lightdm

And continue to use it as before. Below are a screenshots from 18.10:

LightDM Unity
