Ubuntu OS Vagrant environment synchronization problem

[shuoy]

when we do the following

./run.sh

we got the following errors. and if we re-run the above script, the error goes away. My guess is that the Ubnutu OS did not come to fully functioning (to accept ssh) for the first run of ansible-playbook.

Not sure if sleep(2) after vagrant up will fix the problem.

I also meet this kind of problems. Sometimes re-run the scripts may helps.
Sometimes I have to run the scripts 3 times to finish the setting up, but it doesn't reappear now. -_-!
