无人值守-升级不能正常工作

Question

我有过

Welcome to Ubuntu 16.04.5 LTS (GNU/Linux 4.15.0-24-generic x86_64)

15 packages can be updated.
7 updates are security updates.

我看了这几个星期，并尝试了这么多的东西来修复它，但我不能让它运行。无人值守-升级不会升级我的服务器。

我安装了

# apt-get install unattended-upgrades
Reading package lists... Done
Building dependency tree
Reading state information... Done
unattended-upgrades is already the newest version (0.90ubuntu0.9).
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

# apt-get install apt-listchanges
Reading package lists... Done
Building dependency tree
Reading state information... Done
apt-listchanges is already the newest version (2.85.14ubuntu1).
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

这是我的/etc/apt/apt.conf.d/10周期

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";

这是我的/etc/apt/apt.conf.d/50无人值守-升级

Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        "${distro_id}ESM:${distro_codename}";
        "${distro_id}:${distro_codename}-updates";
};

Unattended-Upgrade::Package-Blacklist {
        "open-vm-tools";
};

Unattended-Upgrade::AutoFixInterruptedDpkg "true";
Unattended-Upgrade::MinimalSteps "true";
Unattended-Upgrade::InstallOnShutdown "true";
Unattended-Upgrade::Mail "root";
Unattended-Upgrade::MailOnlyOnError "true";
Unattended-Upgrade::Remove-Unused-Dependencies "true";
Unattended-Upgrade::Automatic-Reboot "true";
Unattended-Upgrade::Automatic-Reboot-Time "07:00";
Acquire::http::Dl-Limit "0";

这就是我在日志文件/var/log/unattended-upgrades/unattended-upgrades.log中的内容。

INFO Initial blacklisted packages: open-vm-tools
INFO Initial whitelisted packages:

INFO Allowed origins are: ['o=Ubuntu,a=xenial', 'o=Ubuntu,a=xenial-security', 'o=UbuntuESM,a=xenial', 'o=Ubuntu,a=xenial-updates']

有人知道出了什么问题吗？

Answer 1

与以上回答 my相反："/etc/apt/apt.conf.d/50unattended-upgrades“确实有：

无人值守-升级：：InstallOnShu倒计时“假”；

但我仍然看到：

欢迎来到Ubuntu18.04.3LTS (GNU/Linux ) 29包可以更新。0更新是安全更新。

那么，为什么这29个软件包没有更新呢？

事实证明，"/etc/apt/apt.conf.d/50unattended-upgrades“还包含以下声明：

无人值守-升级:允许-来源{ "${distro_id}:${distro_codename}"；"${distro_id}:${distro_codename}-security"；//扩展安全维护；不一定存在于//每个发行版，而且这个系统可能没有安装它，但如果//可用，则更新策略是这样的:无人值守-升级//应该从这里默认安装。"${distro_id}ESM:${distro_codename}"；// "${distro_id}:${distro_codename}-updates"；// "${distro_id}:${distro_codename}-proposed"；// "${distro_id}:${distro_codename}-backports"；}；

对我来说，修复的关键是简单地取消对这一行的评论：

// "${distro_id}:${distro_codename}-updates"；

Answer 2

我找到了原因：

Unattended-Upgrade::InstallOnShutdown "true";

这意味着只有在关闭之前才会安装更新。因为这台机器是一台24/7的服务器，所以从来没有发生过更新。

Answer 3

如果在@cuedee跟踪这个答案之后，它仍然无法工作，您可以尝试进行一次试运行，看看是否收到了某种错误消息或警告。

sudo unattended-upgrades -v -d

在我的例子中，输出解释了我的连接是计费的(移动电话的热点)，而且默认情况下，无人值守的升级不允许在计费连接上进行更新。我在/etc/apt/apt.conf.d/50unattended-upgrades中用以下行修改了它：

Unattended-Upgrade::Skip-Updates-On-Metered-Connections "false";
