Well, this is exactly the same installation steps I did for 16.04 except that I had to add MATE ppa since MATE is not provided in the base 14.04 repos.

Installation was done on a LXC container with base ubuntu 14.04 server updated to date.
The process involved in creating the template is basically a debootstrap with minimal install.

To sum up :

* Create the container and login as root
* apt-get update; apt-get dist-upgrade -y
* apt-get install software-properties-common
* add-apt-repository ppa:x2go/ppa
* wget -qO - http://packages.arctica-project.org/archive.key | sudo apt-key add -
* echo "deb http://packages.arctica-project.org/ubuntu trusty main" > /etc/apt/sources.list.d/arctica.list
* apt-get update; apt-get dist-upgrade -y
* apt-get install x2goserver x2goserver-xsession x2gomatebindings mate-core ubuntu-mate-themes mate-applets mate-menus mate-notification-daemon mate-screensaver libcanberra-pulse firefox
* useradd -m -s /bin/bash walid
* passwd walid
* reboot

Then connect with X2Go client but it fails.

Just to let you know, this was a quick test the same way I did on a 16.04 based install (which works nicely) in the same condition.
We have plenty of VMs running X2Go Server on Ubuntu 14.04 for our DEVs, I tried to update one of them with these repos (X2Go Heuler and Arctica) and I got the exact same error so I doubt this is related to an incomplete installation ... at least, not on the base system anyway.

Regards,

Walid

Looks like an inclomplete x2goserver installation.
