=========

# luzifer-ansible / ubuntu-unattended-upgrades
|
||||
|
||||
Enable unattended upgrades on Ubuntu machines
|
||||
This role installs required packages for unattended upgrades and configures them.
|
||||
|
||||
Role Variables
|
||||
--------------
|
||||
## Requirements
|
||||
|
||||
```yaml
|
||||
---
|
||||
mail_target: "mail@example.com" # The email address to send reports to
|
||||
reboot_time: "04:00" # When to reboot the server after updates
|
||||
do_reboot: "true" # Execute an automated reboot?
|
||||
do_autoremove: "false" # Execute 'apt-get autoremove'?
|
||||
```
|
||||
- Ubuntu >= 16.04 (xenial)
|
||||
|
||||
You should ensure `do_reboot` and `do_autoremove` are strings as they are written into the apt configuration and that file expects `true` instead of `True`, which will get written if you pass a bool here.
|
||||
## Usage
|
||||
|
||||

||||
