我已经安装了Debian无人值守升级包。 它升级大部分，但不是所有的软件包。 如果在运行后执行apt-get upgrade ，则会安装更多的软件包。
这是我的/etc/apt/sources.list ：
deb http://ftp.de.debian.org/debian/ squeeze main non-free deb-src http://ftp.de.debian.org/debian/ squeeze main non-free deb http://security.debian.org/ squeeze/updates main non-free deb-src http://security.debian.org/ squeeze/updates main non-free # squeeze-updates, previously known as 'volatile' deb http://ftp.de.debian.org/debian/ squeeze-updates main non-free deb-src http://ftp.de.debian.org/debian/ squeeze-updates main non-free # squeeze backports deb http://backports.debian.org/debian-backports squeeze-backports main contrib non-free # LTS deb http://http.debian.net/debian/ squeeze-lts main contrib non-free deb-src http://http.debian.net/debian/ squeeze-lts main contrib non-free
这是我的/etc/apt/apt.conf.d/50unattended-upgrades文件。 我的猜测是，这个问题可能在前面几行应该匹配我的sources.list条目：
// Automatically upgrade packages from these (origin, archive) pairs Unattended-Upgrade::Allowed-Origins { "${distro_id} stable"; "${distro_id} ${distro_codename}-security"; "${distro_id} ${distro_codename}/updates"; "${distro_id} ${distro_codename}-updates"; "${distro_id} ${distro_codename}-backports"; "${distro_id} ${distro_codename}-lts"; }; // List of packages to not update Unattended-Upgrade::Package-Blacklist { // "vim"; // "libc6"; // "libc6-dev"; // "libc6-i686"; };
以下是日志文件的摘录：

最后，这里是没有安装的软件包。 该行在无人参与升级包运行之后立即执行。
# apt-get upgrade Reading package lists... Done Building dependency tree Reading state information...

请告知如何修复configuration文件，以便这些软件包得到更新。
阅读源代码后，我发现了它。 Debian Squeeze现在被命名为“oldstable”。 这里是Debian Squeeze的相关部分：
// Automatically upgrade packages from these (origin, archive) pairs Unattended-Upgrade::Allowed-Origins { "${distro_id} oldstable"; "${distro_id} ${distro_codename}-security"; "${distro_id} ${distro_codename}-lts"; "${distro_id} ${distro_codename}-updates"; "${distro_id} ${distro_codename}-backports"; };
当我在这里时，这里是Debian Wheezy的configuration文件：
// 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=stable-backports"; // "origin=Debian,archive=stable,label=Debian-Security"; // "origin=Debian,archive=oldstable,label=Debian-Security"; };
