Somehow, my root partition full even though has 3.7GB disk space. I got this error when update my Ubuntu. So the update command just hang at Terminal and little message prompted me for this 
I able to clear some space by this command,
sudo apt-get clean
However, I know there might be some other way which I still looking on. I will keep on share if any update on this topic.
