[chef] Re: Re: Re: yum package resource fails with "ImportError: No module named yum"

Hi,

Since I've previously had this kind of issue (with 2014.03 changing the default ruby), is it possible that you're not locking your repo releasever to 2014.09?

Amazon Linux runs a continuous release system, and version 2015.03 was released today[1].  Unless you've taken steps to keep your existing systems locked to 2014.09, you'll find packages updated to the latest versions.

If that sounds like it might be your problem, search for "How do I lock my AMI to a specific version?" on this page: http://aws.amazon.com/amazon-linux-ami/faqs/

We've seen a few reports of this today.  It would be very helpful if
you could file an issue with these details and we can discuss the best
path forward there.

Cheers,
