unattended #6

Supports: xenial bionic trusty
Add to new model


Configure unattended upgrades and reboots. Report status of pending updates and reboots.


This charm is designed to ensure that the juju unit to which it deploys is optimally-configured for secure, unattended operation, and report a succinct summary of this in its juju status output. It is assumed that the unit is safe to reboot at any time and is part of a well-behaved application which can recover from such reboots automatically.

Configuration items changed:

  • Install unattended-upgrades
  • Set unattended-upgrades to automatically reboot if required
  • Enable verbose boot, automatic file system fixing, and clearing out of /tmp in /etc/default/rcS


How to use this charm:

juju deploy cs:primarycharm
juju deploy ./unattended unattended
juju add-relation primarycharm unattended


By default unattended turns on AUTOMATIC REBOOTS when unattended-upgrades indicates they are needed. If you do not want this, set reboot-time to 'none' or a fixed time.

Set remove-unused to false if you do not want unused apt packages to be removed.
