无人值守升级没有运行

我已经安装了无人值守升级包，并在/etc/cron.daily/apt有一个apt cron，但是没有自动运行。 /var/log/unattended-upgrades/中没有任何内容，并且有待定的升级。

20auto升级看起来像：

 APT::Periodic::Update-Package-Lists "1"; APT::Periodic::Unattended-Upgrade "1"; 

50个无人值守升级看起来像：

 // Automatically upgrade packages from these origin patterns Unattended-Upgrade::Origins-Pattern { // Archive or Suite based matching: // Note that this will silently match a different release after // migration to the specified archive (eg testing becomes the // new stable). // "o=Debian,a=stable"; // "o=Debian,a=stable-updates"; // "o=Debian,a=proposed-updates"; "origin=Debian,archive=stable,label=Debian-Security"; "origin=Debian,archive=oldstable,label=Debian-Security"; }; // List of packages to not update Unattended-Upgrade::Package-Blacklist { // "vim"; // "libc6"; // "libc6-dev"; // "libc6-i686"; }; // This option allows you to control if on a unclean dpkg exit // unattended-upgrades will automatically run // dpkg --force-confold --configure -a // The default is true, to ensure updates keep getting installed //Unattended-Upgrade::AutoFixInterruptedDpkg "false"; // Split the upgrade into the smallest possible chunks so that // they can be interrupted with SIGUSR1. This makes the upgrade // a bit slower but it has the benefit that shutdown while a upgrade // is running is possible (with a small delay) //Unattended-Upgrade::MinimalSteps "true"; // Install all unattended-upgrades when the machine is shuting down // instead of doing it in the background while the machine is running // This will (obviously) make shutdown slower //Unattended-Upgrade::InstallOnShutdown "true"; // Send email to this address for problems or packages upgrades // If empty or unset then no email is sent, make sure that you // have a working mail setup on your system. A package that provides // 'mailx' must be installed. Eg "[email protected]" Unattended-Upgrade::Mail "root"; // Set this value to "true" to get emails only on errors. Default // is to always send a mail if Unattended-Upgrade::Mail is set //Unattended-Upgrade::MailOnlyOnError "true"; // Do automatic removal of new unused dependencies after the upgrade // (equivalent to apt-get autoremove) //Unattended-Upgrade::Remove-Unused-Dependencies "false"; // Automatically reboot *WITHOUT CONFIRMATION* if a // the file /var/run/reboot-required is found after the upgrade //Unattended-Upgrade::Automatic-Reboot "false"; // Use apt bandwidth limit feature, this example limits the download // speed to 70kb/sec //Acquire::http::Dl-Limit "70"; 

我有待升级：

• netcat /通过ssh命名pipe道代理
• 我是否可以使用Gulp来修改我的.htaccess文件，使用Dev＆Production的不同configuration？
• 我最近改变了我的托pipe，现在我只能发送电子邮件，并没有收到使用GMail
• 我在哪里可以从CentOS7获得libcgroup和policycoreutils-python？
• 在Apache中禁用单个文件的https

有谁知道什么是错的？
