Unable to install plasma mobile on Ubuntu 24 LTS

I am attempting to get KDE plasma mobile working on Ubuntu 24 LTS in support of my ongoing White Box Cellphone project.

Here is my process:

apt remove ubuntu-desktop
apt install kde-plasma-desktop
reboot

systemctl enable sddm
systemctl set-default graphical.target

reboot 

add-apt-repository http://archive.neon.kde.org/user
Go and fetch repository key from https://archive.neon.kde.org; add to apt keyring
(again) add-apt-repository http://archive.neon.kde.org/user

apt install plasma-mobile
apt --fix-broken-install

I get errors which seem to indicate conflicts between packages. Are multiple packages trying to control the same files on disk?

Is there a better way to do this? Is there a stable release of plasma mobile that is known to play well with Ubuntu? Do I need to remove & ban some packages from Ubuntu?
