I'm trying to set up my Turtlebot2 on Ubuntu 16.04 from a master PC using this code:

roslaunch turtlebot_bringup minimal.launch

and this is what I receive:


... logging to /home/turtlebot/.ros/log/488f2a6c-70b1-11eb-b8ba-3de1cab3bb36/roslaunch-turtlebot-ThinkPad-X280-7347.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

I also get this same error when trying to launch my Orbecc Astra camera with:
rostopic echo /camera/rgb/image_raw

I don't know where to go from here but it seems to be keeping me from having control over movement and various things connected to my turtlebot. Any tips?
