Is there any way I can install Ubuntu MATE correctly?

Let's look at some of the messages.

Note, selecting 'mate-desktop-environment' instead of 'mate'

apt-get is replacing the package name mate with mate-desktop-environment. Instead of assuming the package is called mate, you could have looked at apt-cache search mate.

 The following packages have unmet dependencies:
 mate-desktop-environment : Depends: mate-desktop-environment-core (= 1.20.0+2~16.04.york0) but it is not going to be installed

This says that the package you asked to install (mate-desktop-environment, was mate) depends on a package called mate-desktop-environment-core. "Depends", in this context means "gotta have it, won't work without it".

To fix just this problem, do:

sudo apt-get install mate-desktop-environment mate-desktop-environment-core

However, all the Recommends: lines recommend other packages that make mate more useful. You could simply add the packages you want to the command line. My apt-cache search mate | grep -w mate | wc -l shows 120 packages with mate in their names. Investigate them. Start with apt-cache search mate | grep -w mate.

I am assuming you are trying to install the packages using the ppa:jonathonf/mate-1.20 or ppa:jonathonf/mate-1.20-gtk3.22 repositories.

I found the root cause of the above errors to be that only older versions of GTK were available.

I found that running the commands added all the necessary packages to allow a full install of the mate desktop environment.

sudo add-apt-repository ppa:jonathonf/mate-1.20-gtk3.22
sudo add-apt-repository ppa:jonathonf/gtk3.22
sudo apt update
sudo apt install mate-desktop-environment
