Install NoMachine on Ubuntu 20.04

Download NoMachine Installation Package

NoMachine is not available on Ubuntu 20.04 default repositories. Therefore, you need to download the DEB binary package from NoMachine For Linux Downloads page.

On the Download page, select the version of NoMachine for your respective Ubuntu 20.04 system architecture.

To find your Ubuntu system architecture type, use hostnamectl or uname -m command;

hostnamectl
    Static hostname: ubuntu20.kifarunix-demo.com
         Icon name: computer-vm
           Chassis: vm
        Machine ID: d91cc24f09bc439190b19b1fe11365b0
           Boot ID: bf5cd9c49eed4e46a7903d183303cb84
    Virtualization: oracle
  Operating System: Ubuntu 20.04.1 LTS
            Kernel: Linux 5.4.0-65-generic
      Architecture: x86-64

or

uname -m
x86_64

In our case, we will download the DEB binary package for the 64-bit Ubuntu 20.04 system. You can simply navigate to NoMachine x86_64 Debian Binary packages page and grab your package. Or simply execute the command below to download NoMachine version 7.1.3_1, which is the current stable release version of NoMachine as of this writing. You can verify the versions and replace accordingly.

Allow NoMachine Remote Connection

NoMachine installed on a remote system acts as the server. If the server is running unattended, then you need to disable the need for permission to connect to it remotely. Otherwise, if it is being managed, then you can leave the default settings to be prompted on whether to allow remote access.

So, since in our case we are running our Ubuntu 20.04 system unattended, we uncheck the Require permission to let users connect option.
