I have a cloud config file defined on my EC2 instance in the user data. Many of the parts/actions are run by the server properly, but package installation seems to fail invariably:
#cloud-config
package-update: true
package-upgrade: true
# ...
packages:
- puppet3
- lvm2
- btrfs-progs
# ...
I see the following in the logs:

When I actually run the command yum -t -y install puppet3 lvm2 btrfs-progs as root, it just runs fine, but Cloud Init is failing to run it on its own.
Is there something I'm doing wrong here?
Evidently there was a bug fixed with later versions of the image. If this is happening to you, it may be a legitimate bug in Cloud-Init or your servers implementation of it. A package upgrade may fix the problem, also an update to the image will fix it globally.
