无人值守升级

无人值守升级中有两个具有相同配置设置的文件/etc/apt/apt.conf.d：

20auto-upgrades和10periodic。

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "1";

  1. 有什么不同？

  2. 为了AutoCleanInterval工作，我是否需要在中设置以下选项/etc/apt/apt.conf.d/50unattended-upgrades：

    Unattended-Upgrade::Remove-Unused-Dependencies "true";

更新： 不确定这些选项是否有效。在以下测试中，与 apt update 相比，unattended 非常快。我不知道为什么：

abhishek ~ $ time sudo unattended-upgrade -v

答案1

干得好：

  • 内容之间没有区别，只是由于 的升序解析行为，10periodic会比 更早解析。如果在两个不同的文件（或更多）中提到了相同的指令，则较早的指令将被最后一个指令覆盖。20auto-upgradesapt

  • 不。

    APT::Periodic::AutocleanInterval/var/cache/apt/archives采取一个整数值并设置删除和中的本地缓存包的间隔/var/cache/apt/archives/partial，因此它类似于sudo apt-get clean。

    另一方面，Unattended-Upgrade::Remove-Unused-Dependencies采用布尔值并且类似于命令sudo apt-get autoremoveie 将删除任何已安装包未使用的所有依赖项。

要启用Unattended-Upgrade，您需要有以下指令：

APT::Periodic::Unattended-Upgrade

任何文件中的定义都位于Unattened-Upgrade定义之前（例如，定义通常放在中/etc/apt.conf.d/50unattended-upgrades）。

示例值如下：

APT::Periodic::Unattended-Upgrade "1"; ## Runs "Unattened-Upgrade" daily
APT::Periodic::Unattended-Upgrade "7"; ## Runs weekly

至于何时apt运行这个（和其他），它每天运行，并且操作在文件中定义/etc/cron.daily/apt。

在我的系统上，cron文件于/etc/cron.daily/上午 06:26 开始运行：

25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
