When is 16.04 going to be officially available on AWS? [closed]
It doesn't seem to be avail on http://cloud-images.ubuntu.com/locator/ec2/ nor I can find any when searching on AWS itself
They are kind of released.
If you look at: https://cloud-images.ubuntu.com/query/xenial/server/released.current.txt you will find the AMI id's.
As of right now though, they are not public, atleast not in eu-west-1. Most likely Amazon is vetting them, because they'll become official images.
