Comment 1 for bug 1791185

images.maas.io gets its images from cloud-images.ubuntu.com/daily so this effects all cloud-image users, not just MAAS. I think we should have a larger discussion with foundations as to whether the image should include the apt list cache.

Also instead of removing the current apt cache we could force apt-get update to be run on first boot[1]. We need to be careful not to do this in the ephemeral environment as in some situations the ephemeral environment can be used without using apt at all currently.
