Error while launching any .launch file

Question

Hi all,

I'm getting this error

machine.env_loader must have been assigned before creating ssh child instance
The traceback for the exception was written to the log file

when running any .launch file on my local machine( I'm not using ssh at all)

I'm using ubuntu 16.04 + ROS kinetic

I have to admit that I missed up with /etc/hosts and ROS_MASTER_URI but I don't know what I did wrong :)

I'm not sure it's actually related, but what did you do to /etc/hosts and what is the value of ROS_MASTER_URI now?
