Ubuntu Unattended upgrades package interferring

Hi. Not even sure this is the right place to ask this but...

On a packer AMI for a KitchenCI image of both trusty + xenial I am testing a cookbook for, I forgot to turn off periodic upgrades (unattended-updates package).

Outcome: Kitchen boots the instance, connects, wgets Chef and fails.

Question: Wouldn't it make sense to let the user know that, if this package is installed, and dpkg fails to pull a lock, that this might be the cause for the issue? I mean neither does it have to be the issue, nor do I want to propose anything more than a helpful message.
