# Revision history [back]

This was the fix, apparently epel just isn't enabled by default even when the system needs packages that are only available in epel

I'll also note that I was able to discover this upon looking at the yum history of the resulting image from diskimage-builder, it had the following for one of my entries:

You can see right there it's attempting to install jq and later it will attempt to install puppet but can't, because there's no place to find it. This becomes more apparently when you really take a fine look at the log for diskimage-builder.

Edit: I'll note that you don't need to modify the elements/centos7/elements-deps file at all, just tack on epel to the diskimage-builder command ie: diskimage-builder/bin/disk-image-create vm {...} epel {...}
