Public bug reported:
I use the following cloud-init configuration works perfectly for Ubuntu
14.04, Ubuntu 16.04, Debian 8, Debian 9 and Centos 7 but not with the
new Ubuntu 18.04
--- 8< 8< 8< ---
#cloud-config
datasource:
Ec2:
strict_id: false
hostname: my_cloudserver_name
phone_home:
url: http://169.254.169.254/2009-04-04/done
post: [ instance_id ]
tries: 10
users:
- default
ssh_authorized_keys:
- "ssh-rsa AAA ....=="
--- 8< 8< 8< ---
The installation process hangs here and will fail:

interface on EC2.

after adding:

packages:

the cloud-init works as wished.

It seems there is a dependency in cloud-init to the pre-netplan
networking system in 18.04.
