Error when installing ROS INDIGO on a real NAO V4

edit

Greetings

I am new with ROS and I am experiencing some issues while installing ROS INDIGO on my (real) NAO V4 Robot. I followed the guide, where during the installation on my virtual box I found out that the Cholmod library could not be found and rosdep install --from-path src -i -y could not be resolved. Nevertheless, the roscore can be ran on the virtual nao and on the real nao.

However, when roslaunch nao_bringup nao_full.launch force_python:=true both on the virtual nao and the real nao, the naoqi_driver has some issues due to the PYTHONPATH, below is the log from the real NAO, plz help me!

I've read multiple pre-existing threads about similar issues but could not work something out.

Using ctc-linux64-atomv2.1.2.17 , opennao-vm-2.1.2.17.ova, naoqi-sdk-2.1.2.17-linux64, pynaoqi-python2.7-2.1.2.17-linux64
