Is there a Ubuntu Mate for Raspberry Pi 4?

if you want a stable and easy solution simply install mate in raspbian:

1. apt-get update
2. Install mate
   sudo apt-get install mate-core mate-desktop-environment
3. Add mate as default environment for your user by adding this line
   sudo update-alternatives --config x-session-manager
   In the wizard, type the number corresponding to mate
4. Reboot
   sudo reboot
