Thank you Pinar for your answer.

I am not working with Ubuntu team, but I received the mail :

Does the ROS crowd read this? Or does this need to be reported somewhere
else?

As I taught it was for me, I answered.

But as I met the same problem I will share with you my experience:

Indeed, it's a ROS problem.
I tried a lot of things to solve the problem, but all failed.
I reported the problem to Ubuntu, but the answer took times to come.
So I saved all my data in an external hard drive and formatted the disk 
with the version 16 of Ubuntu.
Unlike Windows, when one install Ubuntu, a set of useful softwares 
installs automatically with, so I did not have much to install and 
configure behind, then things went fast.

Best regards

Mohamed Zouhair HARBACHI
