Yes I have the aarch64 and running theĀ wget https://www.nomachine.com/free/arm/v8/deb -O nomachine.deb command and theĀ
sudo dpkg -i nomachine.deb command to install.
Its working and I am connected now replying to this message using NoMachine. Its a little laggy when I type but my local network traffic is high as I am moving 39GB to another computer on the network so will check the speed once the transfer is complete.
Thanks so much for your help I would have never got it working without your help. Hopefully my experience will help others in the future.
