Dear all, I'm doing tutorials, and installation of turtlesim gets stuck after the prompt shows "---> building boost". After 20 minutes passed since the message was shown, I terminated the process which was "$ rosdep install turtlesim", ran the same command again, but it stays the same. Could anyone tell me if there's a solution to this?
