Sorry, but I'm still not clear on what your trying to achieve. Add Mate to Ubuntu? For that just add the meta pack:

sudo apt install ubuntu-mate-core

This is now dated (14.04), but the packages are still in use.

Trying to understand the Mate Core Packs

I have a core install running, but I’m wondering if this is truly a minimal install. I first tried installing xorg, marco and mate-desktop to a console only install. This did not work, but if I add mate-desktop-environment-core I then have a working desktop. Which is much less than a standard desktop with about 1000 installed packages and taking up 2 gig of HDD space. So the question; is this the minimal install or will another mix yield less.
