Install NoMachine on Debian 12

Last Updated:

Welcome to our tutorial on how to install NoMachine on Debian 12. NoMachine is a remote desktop tool just like VNC, TeamViewer. It is designed to work across several platforms such as Windows, Mac and Linux to give users access to the physical desktop of the remote computer. NoMachine provides the best, fastest and highest quality remote desktop experience.

Installing NoMachine on Debian 12

Install NoMachine

Note that in order for NoMachine to work, you need to install both on the remote desktop system you need to access as well as on the desktop system you are connecting from.

NoMachine is not available on Debian 12 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 Debian 12 system architecture.

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

hostnamectl | grep Architecture:

Sample output

      Architecture: x86-64


uname -m

In our case, we will download the DEB binary package for the 64-bit Debian 12 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 debian binary. Replace the value of VER with the current stable release version of NoMachine.


Once the download is done, run either of the commands below to install the package;

sudo dpkg -i nomachine_${VER}_amd64.deb

Or simply run;

sudo apt install ./nomachine_${VER}_amd64.deb
