Errors with installing Freenx on ubuntu

Question

I am trying to install remote desktop on an ubuntu ec2 instance by using NX, i have done sudo -E apt-get update & sudo -E apt-get install -y ubuntu-desktop. then to install freenx sudo add-apt-repository ppa:freenx-team but from here forward when I do sudo apt-get update it gives me some errors:

Err http://ppa.launchpad.net trusty/main amd64 Packages 404 Not Found

Ign http://ppa.launchpad.net trusty/main Translation-en_US

Ign http://ppa.launchpad.net trusty/main Translation-en

W: Failed to fetch http://ppa.launchpad.net/freenx-team/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead

Then when I type sudo aptitude install -y freenx it gives me another error which is:

"Couldn't find any package whose name or description matched "freenx"

I have googled it and found different suggestions but none of them works, it became a real headache for me, appreciate your help.

Answer 1

You probably want to remove your old ppa first with:

sudo add-apt-repository --remove ppa:freenx-team

Then I think you need to try the command below for trusty and new versions of ubuntu. Note the /trusty on the end.

sudo apt-add-repository ppa:freenx-team/trusty

On my machine I had to use aptitude rather than apt-get for some reason unknown to me.

Answer 2

freenx is not available for trusty yet, the latest supported ubuntu distro is precise. So if you want to install it then you probably need to download it from the ubuntu precise repository.

Go here to see the list of ubuntu distros supported by freenx

There is another way too, but I can't guarantee that either of these process will work, because of dependency issues.

The second way you can try installing this is to edit the ppa file that was created for that ppa. It's located in /etc/apt/sources.list.d/
look for a file named closely that of your software name and open it with root privilege and replace any trusty with precise and save the file then run sudo apt-get update and then sudo apt-get install freenx
