Title:
cloud-init disables user on azure at second reboot
Status in cloud-init:
Confirmed
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hello,
Environment:
platform: Azure
arm image: Canonical UbuntuServer 16.04-DAILY-LTS latest
Steps:
Deploy VM with user/pass authentication
Install latest linux-next-upstream kernel (for example 4.19.0-4db9d11bcbef,
where 4db9d11bcbef is the git tag from the linux-next latest tree:
https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/)
reboot (all good)
reboot again
cloud-init disables the username password authentication
I checked the cloud-init logs and found:
2018-11-01 16:45:28,566 - init.py[INFO]: User already exists, skipping.
2018-11-01 16:45:28,570 - util.py[DEBUG]: Running command ['passwd', '-l',

This issue is very bad one, as it can render your vm inaccessible on Azure.
I think this problem is due to the new kernel installation.
