I am trying to updated OpenCr by following these instructions

http://emanual.robotis.com/docs/en/platform/turtlebot3/opencr_setup/



I keep encountering following error after running these steps.



```

export OPENCR_PORT=/dev/ttyACM0

export OPENCR_MODEL=burger

rm -rf ./opencr_update.tar.bz2

wget https://github.com/ROBOTIS-GIT/OpenCR-Binaries/raw/master/turtlebot3/ROS1/latest/opencr_update.tar.bz2 && tar -xvf opencr_update.tar.bz2 && cd ./opencr_update && ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr && cd ..

```



Here is the output I am getting.
