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.
