Now I’ve got it working on Hardy (Ubuntu 8.04 fresh install) following just this three steps:

1.- Add to /etc/apt/sources.list:
deb http://ppa.launchpad.net/marceloshima/ubuntu hardy main
deb-src http://ppa.launchpad.net/marceloshima/ubuntu hardy main

2.- sudo apt-get update

3.- sudo aptitude install freenx

Is there any difference with your method?

With respect the error messages “No such file or directory”, can you please check that /usr/NX/var/db exists and has the correct permissions? Also, you can trying enabling full logging in /usr/NX/etc/node.cfg and see if it casts additional information.

You might also want to try: ssh -X myserver; /usr/NX/bin/nxnode –agent to test the basic functionality. Session log follows:

I will appreciate any help.
Thank you.
