'error wrong architecture - run dpkg -add-architechture to add it and update afterwards'.
So I installed the arm64 image from RealVNC download and then obviously got this error as I'm running the arm64 Ubuntu Mate and RealVNC only offer an armhf one: I'm trying to get VNC running on the above and I'll try and quickly run down how I managed to get to the position where it's almost working.
