无人值守的升级触发无声重新启动

Question

在过去的几个星期里，我工作了几次，突然我的桌面消失了，我的机器完全重新启动。

在今早再次发生这种情况之后，我通过syslog跟踪了它，我能找到的最接近的事件可能是unattended-upgrades.service: Succeeded：

Jul 14 10:02:42 pc charon: 05[NET] sending packet: from 192.168.1.214[4500] to 123.321.123.321[4500] (92 bytes)

我并不反对正常的无人值守的升级，但是没有警告的无声重启是非常糟糕的。今天早上，我打开了15个窗口，并且正在调试一些棘手的代码。我花了30分钟才回到原来的地方。

无声的重启是否带有无人参与的升级，这是正常/可配置的吗？

阻止这种重新启动发生的推荐方法是什么？

奇怪的是，它似乎没有被配置为这样做：

$ grep -irnC2 reboot /etc/apt/apt.conf.d/

无论无人值守升级是否重新引导您的系统，系统都由配置文件/etc/apt/apt.conf.d/50unattended-upgrades中的条目控制。

我的文件被设置为不允许重新启动(默认)，文件的相关部分如下所示

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

// If automatic reboot is enabled and needed, reboot at the specific
// time instead of immediately
//  Default: "now"
//Unattended-Upgrade::Automatic-Reboot-Time "02:00";
