Please cross check the tutorials if everything is correct. This definitely has to do with the roscore only as the error clearly mentions the master is not available. It could also be the networking issue as the roscore running on the turtlebot is not detected by the workstation. Please cross check with the setup and test the networking with the testing procedure i have mentioned in this answer. Hope it helps

Check three places where you might have to check the setup 1. /etc/hosts 2. ~/.bashrc 3. ~/ros_workspace/setup.h
Check for the MASTER_URI and HOST_URI in the ~/.bashrc
