I just updated my system (System76, Onx Pro) with the latest ubuntu16 software (software updater) .Now when I run roscore it just hangs. I get the following if I ctl-c. Any idea on what is going on greatly appreciated. Update applied Aug 8.

richard@rjn:~$ roscore

I seem to have had an issue with setting my ROS_IP address. Sorry for the panic.

I have same problem. roscore can't start. Process stop after "Done checking log file disk usage. Usage is <1GB."

My reason is wrong ROS_IP. I have registered IP which is not used now. I changed ROS_IP and then roscore become to start.

export ROS_MASTER_URI=http://localhost:11311/ export ROS_HOSTNAME=127.0.0.1 export ROS_IP=127.0.0.1
