Hello,
i have installed the image on my linux mint 17.3.
I can't access localhost:8888.

I connected to the machie through ssh and started chef.

my log is:
`vagrant@vagrant-ubuntu-trusty-64:~$ sudo chef-client
Starting Chef Client, version 12.14.89

Chef encountered an error attempting to create the client "vagrant-ubuntu-trusty-64"

I have tried this also in windows 10, same errors seen.
What can I do? Thanks!

I made a fork, with some adjustments. It is working for me (Windows 7). https://github.com/rreben/Mining-the-Social-Web-2nd-Edition It is reported to work on windows 10 and MacOS as well.
