*** Chef 10.18.2 ***
apt            [1.9.0]

odd.. unless it has something to do with my squid-deb-proxy?
I read over the recipe and It's supposed to delete the /var/lib/apt/periodic/update-success-stamp but that doesnt seem to happen at my end.. I'll debug it tomorrow. 

If it's working for you then I'll remove the forced update.
