Overview

The unattended_upgrades module allows for the installation and configuration of automatic security (and other) updates through apt.

This functionality used to be part of the puppetlabs-apt module but was split off into its own module.

Module Description

The unattended_upgrades module automates the configuration of apt package updates.

Setup

What unattended_upgrades affects

  • Package/configuration for unattended_upgrades

Beginning with unattended_upgrades

All you need to do is include the apt module, include apt, and this module, include unattended_upgrades for it to work.

This module relies on the apt module and will not work without it.

Usage

Using unattended_upgrades simply consists of including the module and if needed altering some of the default settings.

Reference

Classes

  • unattended_upgrades: Main class, installs the necessary packages and writes the configuration.

Parameters

unattended_upgrades

  • age ({}): A hash of settings with two possible keys:

    • min (2): Minimum age of a cache package file. File younger than min will not be deleted.
    • max (0): Maximum allowed age of a cache package file. File older than max will be deleted.

    Any of these keys can be specified and will be merged into the defaults:

    class { 'unattended_upgrades':
  age => { 'max' => 10 },
}

  • auto ({}): A hash of settings with these possible keys:

    • clean(0): Remove packages that can no longer be downloaded from cache every X days (0 = disabled). Also supports 'always' as value to execute this operation every time the script is executed.
    • fix_interrupted_dpkg(true): Try to fix package installation state.
    • reboot(false): Reboot system after package update installation.
    • reboot_withusers(true): If automatic reboot is enabled and needed, reboot even if there are users currently logged in.
    • reboot_time(now): If automatic reboot is enabled and needed, reboot at the specific time (instead of immediately). Expects a string in the format "HH:MM", using the 24 hour clock with leading zeros. Examples: "16:37" for 37 minutes past 4PM, or "02:03" for 3 minutes past 2AM.
    • remove(true): Remove unneeded dependencies after update installation.

    Any of these keys can be specified and will be merged into the defaults:

    class { 'unattended_upgrades':
  auto => { 'reboot' => true },
}

  • backup ({}): A hash with two possible keys:

    • archive_interval (0): Backup after n-days if archive contents changed.
    • level (3): Backup level.

    Any of these keys can be specified and will be merged into the defaults:

    class { 'unattended_upgrades':
  backup => { 'level' => 5 },
}

  • blacklist([]): A list of packages to not automatically upgrade.

  • dl_limit(undef): Use a bandwidth limit for downloading, specified in kb/sec.

  • enable (1): Enable the automatic installation of updates.

  • install_on_shutdown (false): Install updates on shutdown instead of in the background.

  • mail: A hash to configure email behaviour with the following possible keys:

    • report (undef): Possible values are "always", "only-on-error" or "on-change". Defaults to "on-change". Note that "never" is achieved by not setting any to address.
    • only_on_error (true): Only send mail when something went wrong. Deprecated in unattended-upgrades 1.13 and newer in favor of report.
    • to (undef): Email address to send email too

    If the default for to is kept you will not receive any mail at all. You'll likely want to set this parameter.

    Any of these keys can be specified and will be merged into the defaults:

    class { 'unattended_upgrades':
  mail => { 'to' => 'admin@domain.tld', },
}

  • minimal_steps (true): Split the upgrade process into sections to allow shutdown during upgrade.

  • origins: The repositories from which to automatically upgrade included packages.

    The default origins can be replaced with contents of an array:

    class { 'unattended_upgrades':
  origins => [
    'origin=${distro_id},suite=${distro_codename}',
    'origin=${distro_id},suite=${distro_codename}-security',
    'origin=${distro_id},suite=${distro_codename}-backports',
    'origin=${distro_id},suite=${distro_codename}-updates',
  ],
}

  • extra_origins: Additional repositories from which upgrades should be included. Can be used, if the default origins should be kept.

  • package_ensure (installed): The ensure state for the 'unattended-upgrades' package.

  • random_sleep (undef): Maximum amount of time (in seconds) that the apt cron job can sleep before the execution. The exact amount of time will be random but up to the value specified. The purpose is to avoid that servers/mirrors get hammered at exactly the same time when a lot of machines are switched on, e.g. 9:00 in the morning. Note: If this is left unset, the default value in the apt cron job applies, which is 1800 seconds.

  • size (0): Maximum size of the cache in MB.

  • update (1): Do "apt-get update" automatically every n-days. Also supports 'always' as value to execute this operation every time the script is executed.

  • upgrade (1): Run the "unattended-upgrade" security upgrade script every n-days. Also supports 'always' as value to execute this operation every time the script is executed.

  • days ([]): Set the days of the week that updates should be applied. The days can be specified as localized abbreviated or full names. Or as integers where "0" is Sunday, "1" is Monday etc.

  • upgradeable_packages ({}): A hash with two possible keys:

    • download_only (0): Do "apt-get upgrade --download-only" every n-days. Also supports 'always' as value to execute this operation every time the script is executed.
    • debdelta (1): Use debdelta-upgrade to download updates if available.

    Any of these keys can be specified and will be merged into the defaults:

    class { 'unattended_upgrades':
  upgradeable_packages => { 'debdelta' => 1, },
}

  • verbose (0): Send report mail to root.

  • remove_new_unused_deps (undef): Automatic removal of newly unused dependencies after the upgrade.

  • remove_unused_kernel (undef): Remove unused automatically installed kernel-related packages.

  • syslog_enable (undef): Enable logging to syslog. Default is False.

  • syslog_facility (undef): Specify syslog facility. Default is daemon.

  • only_on_ac_power (undef): Download and install upgrades only on AC power. Default is true.

  • allow_downgrade (undef): Allow package downgrade if Pin-Priority exceeds 1000. Default is false.

Limitations

This module should work across all versions of Debian, Ubuntu, and Linux Mint.
