我的/etc/apt/apt.conf.d/50unattended-upgrades看起来几乎和默认值一样.

// Automatically upgrade packages from these (origin,archive) pairs
Unattended-Upgrade::Allowed-Origins {
        "Ubuntu karmic-security";
        "Ubuntu karmic-updates";
};

// List of packages to not update
Unattended-Upgrade::Package-Blacklist {
//      "vim";
//      "libc6";
//      "libc6-dev";
//      "libc6-i686";
};

// 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. The package 'mailx'
// must be installed or anything that provides /usr/bin/mail.
Unattended-Upgrade::Mail "pupeno@example.com";


// Automatically reboot *WITHOUT CONFIRMATION* if a 
// the file /var/run/reboot-required is found after the upgrade 
//Unattended-Upgrade::Automatic-Reboot "false";

目录/ var / log / unattended-upgrades /为空.运行/etc/init.d/unattended-upgrades start并不是很好：

root@mozart:~# /etc/init.d/unattended-upgrades start
Checking for running unattended-upgrades: root@mozart:~#

似乎有些东西被破坏了,但我不确定为什么.

我有待处理的更新,但它们未被应用：

root@mozart:~# aptitude safe-upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Reading extended state information

The following packages will be upgraded:
  linux-libc-dev 
1 packages upgraded,0 newly installed,0 to remove and 0 not upgraded.
Need to get 0B/743kB of archives. After unpacking 4096B will be used.
Do you want to continue? [Y/n/?]

在我拥有的所有服务器中,无人值守的升级似乎已被禁用：

root@mozart:~# apt-config shell UnattendedUpgradeInterval APT::Periodic::Unattended-Upgrade
root@mozart:~#

有什么想法我错过了什么？
