I noticed you submitted this topic to the ARM category, so I’m assuming that you need a package for ARM. So first check that you are downloading the right package for the architecture you have. You can check this by running ‘uname -m’ in a terminal on the ARM device.
‘aarch64’ means you have ARMv8 and you should install this package:
https://downloads.nomachine.com/download/?id=118&distro=ARM
You can run this command from a terminal to get it:
wget https://www.nomachine.com/free/arm/v8/deb -O nomachine.deb
‘armv7l’ means that you have ARMv7, and so you should install this:
https://downloads.nomachine.com/download/?id=113&distro=ARM
You can run this from a terminal to get it:
wget https://www.nomachine.com/free/arm/v7/deb -O nomachine.deb
and then:
sudo dpkg -i nomachine.deb
to install.
