Kodi will not install on ubuntu mate 20.04/Raspberry Pi 4

Hello
I was wondering if anyone else had this problem and managed to fix it. The directions said to type these lines in terminal.
sudo add-apt-repository ppa:team-xbmc/ppa
sudo apt-get update
sudo apt-get install kodi
which ends up saying a bunch of not installable packages
E: Unable to correct problems, you have held broken packages
then I read someplace this is not for ARM ubuntu. I had Kali, and Raspian on there and had no problem installing Kodi anyone know what I am doing wrong?
Thank you

Kodi is available in the Ubuntu repos: https://packages.ubuntu.com/focal/kodi

sudo apt-add-repository -- remove ppa:team-xbmc/ppa
sudo apt update
sudo apt autoremove
sudo apt install kodi

Thank you I appreciate your help.
