+# This file understands the following apt configuration variables:
+# Values here are the default.
+# Create /etc/apt/apt.conf.d/10periodic file to set your preference.
+#
+# All of the n-days interval options also accept the suffixes
+# s for seconds, m for minutes, h for hours, d for days or
+# the "always" value to do the action for every job run,
+# which can be used with systemd OnCalendar overrides to
+# define custom schedules for the apt update/upgrade jobs.
+#
+#  Dir "/";
+#  - RootDir for all configuration files
+#
+#  Dir::Cache "var/cache/apt/";
+#  - Set apt package cache directory
+#
+#  Dir::Cache::Archives "archives/";
+#  - Set package archive directory
+#
+#  APT::Periodic::Enable "1";
+#  - Enable the update/upgrade script (0=disable)
+#
+#  APT::Periodic::BackupArchiveInterval "0";
+#  - Backup after n-days if archive contents changed.(0=disable)
+#
+#  APT::Periodic::BackupLevel "3";
+#  - Backup level.(0=disable), 1 is invalid.
+#
+#  Dir::Cache::Backup "backup/";
+#  - Set periodic package backup directory
+#
+#  APT::Archives::MaxAge "0"; (old, deprecated)
+#  APT::Periodic::MaxAge "0"; (new)
+#  - Set maximum allowed age of a cache package file. If a cache 
+#    package file is older it is deleted (0=disable)
+#
+#  APT::Archives::MinAge "2"; (old, deprecated)
+#  APT::Periodic::MinAge "2"; (new)
+#  - Set minimum age of a package file. If a file is younger it
+#    will not be deleted (0=disable). Useful to prevent races
+#    and to keep backups of the packages for emergency.
+#
+#  APT::Archives::MaxSize "0"; (old, deprecated)
+#  APT::Periodic::MaxSize "0"; (new)
+#  - Set maximum size of the cache in MB (0=disable). If the cache
+#    is bigger, cached package files are deleted until the size
+#    requirement is met (the oldest packages will be deleted 
+#    first).
+#
+#  APT::Periodic::Update-Package-Lists "0";
+#  - Do "apt-get update" automatically every n-days (0=disable)

+#  - Do "apt-get upgrade --download-only" every n-days (0=disable)
+#
+#  APT::Periodic::Download-Upgradeable-Packages-Debdelta "1";
+#  - Use debdelta-upgrade to download updates if available (0=disable)
+#
+#  APT::Periodic::Unattended-Upgrade "0";
+#  - Run the "unattended-upgrade" security upgrade script 
+#    every n-days (0=disabled)
+#    Requires the package "unattended-upgrades" and will write
+#    a log in /var/log/unattended-upgrades

+#  APT::Periodic::AutocleanInterval "0";
+#  - Do "apt-get autoclean" every n-days (0=disable)
+#
+#  APT::Periodic::CleanInterval "0";
+#  - Do "apt-get clean" every n-days (0=disable)
+#
+#  APT::Periodic::Verbose "0";
