How To Change The DE In The "Live Environment"

[polish-penguin-dev]

Describe the question

I'm trying to download the Cinnamon desktop environment for my Ubuntu-based distro. After installing Cinnamon, and changing it to the default DE, it still uses GNOME in the live environment ("Try Ubuntu"). Is there any way to change this?

What you have tried

I've used the following code:

apt update
add-apt-repository universe
apt install cinnamon -y
update-alternatives --config x-session-manager

I've made sure to select Cinnamon when changing the DE. But, when I try it out, it still remains in GNOME.

In Ubuntu, when I run update-alternatives --display x-session-manager I get back that Cinnamon indeed is the current DE. Running cinnamon tells me screen 0 already has a window manager, and running cinnamon --replace seems to work for a bit before I get the white "Oh no! Something has gone wrong!" screen.

Expected behavior

After running the code I have tried, Cinnamon should have been the DE used in the live environment.
