# APT::Periodic::Download-Upgradeable-Packages-Debdelta "1";
# Requires the package "unattended-upgrades" and will write
# a log in /var/log/unattended-upgrades
#
-# "APT::Archives::MaxAge",
-# - Set maximum allowed age of a cache package file. If a cache
-# package file is older it is deleted (0=disable)
-#
-# "APT::Archives::MaxSize",
-# - 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 biggest packages will be deleted
-# first).
+# APT::Periodic::AutocleanInterval "0";
+# - Do "apt-get autoclean" every n-days (0=disable)
#
-# "APT::Archives::MinAge"
-# - Set minimum age of a package file. If a file is younger it
-# will not be deleted (0=disable). Usefull to prevent races
-# and to keep backups of the packages for emergency.
-#
+# APT::Periodic::Verbose "0";
+# - Send report mail to root
+# 0: no report (or null string)
