FreeNX is pretty old and unmantained. You should try X2GO which uses same NX technology. It's actively developed. For the server installation type:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver

For details you have a detailed guide here: You can install the client also by running:

sudo apt-get install x2goclient

How do you start the service up? when I tried: x2godesktopsharing x2godesktopsharing: cannot connect to X server – slashdottir Oct 8 '14 at 0:49
Thanks a lot for that tip! – Daniel Holm Oct 22 '14 at 16:26
sudo add-apt-repository ppa:freenx-team/trusty
sudo apt-get update
sudo apt-get install freenx-server

Some websites report success using ppa freenx-team/testing (instead of freenx-team/trusty). But that didn't work for me

This is interesting - at least it almost works. But where do you get a freenx client for version 3.2 for Windows? – slashdottir Oct 8 '14 at 0:48
@slashdottir: You can use OpenNX client to connect to the nxserver: – biocyberman Oct 24 '14 at 18:24

Try to use gdebi, it should take care of any dependency that needs to be downloaded:

sudo gdebi -i <packagaename.deb>

If it's not installed, just type first:

sudo apt-get install gdebi
