有大量关于禁用无人值守升级的线程。我知道他们。
我的不满是用户体验还有unattended-upgrade很多不足之处。任务栏中的项目（xubuntu 的右上角）将是放置“无人值守升级正在运行。完成 47%。按此处停止它一次”小部件的地方。我猜那是不存在的。
我有一台不常使用的旧的、低功耗的笔记本电脑，当我启动它时，由于无人值守升级，大多数情况下它会在启动后长达 15 分钟内缓慢爬行。
所以偶尔我想停下来。ps -ef | grep -v grep | grep unattended-upgrade显示一个似乎忽略终止信号的 PID，所以这不是要走的路。apt仅仅杀死和听起来也很危险dpkg。
所以：有没有办法安全地停止一个已经开始的unattended-upgrade？或者是我唯一的选择：
apt-get install new-shiny-tool?
我试图让无人值守升级在我的 Linux Mint 18.3 (Sylvia) 系统上运行，但没有成功。我etc/apt/apt.conf.d/50unattended-upgrades的是标准的：
Unattended-Upgrade::Allowed-Origins {
"${distro_id}:${distro_codename}";
"${distro_id}:${distro_codename}-security";
etc.
但是当我运行它时，它永远找不到任何升级。这是输出sudo unattended-upgrades -d
Initial blacklisted packages:

但是，我在 GUI 更新管理器中列出了一个升级，用于 unrar-nonfree。变更日志的第一行是unrar-nonfree (1:5.3.2-1+deb9u1build0.16.04.1) xenial-security; urgency=medium
我怎样才能让无人值守升级寻找 xenial 升级，以及 sylvia？
我最近在我的台式电脑上安装了 Trisquel 8.0 LTS (Flidas)，它在 Trisquel 7.0 上运行了 4 年。系统变得非常缓慢。当我检查 RAM 和 CPU 使用率时，我发现 CPU 几乎处于 100 % 我top调整看看出了什么问题，发现它unattended-upgr正在消耗整个 CPU。
我试图通过 PID 杀死它，sudo kill 1803但过了一段时间，它又自动启动了。我知道无人值守升级旨在自动安装重要的安全更新，但我需要禁用它自动启动。
我怎么做？
在配置中我看到选项
Unattended-Upgrade::Mailin /etc/apt/apt.conf.d/50-unattended-upgrades)/etc/apt/apt.conf.d/20auto-upgrade.但是，我想要的是：
可以以某种方式设置吗？
我正在使用Ubuntu 16.04并启用了自动更新和重启。版本unattended-upgrades是0.90ubuntu0.9.
当有挂起的重新启动并且我登录到服务器时，我会不断收到这些通知到我的会话：

我是否可以阻止这些消息被发送到 shell，因为接收它们很烦人并且用户知道服务器可能会在维护窗口期间重新启动？我检查了/etc/apt/apt.conf.d/50unattended-upgrades但我发现那里只有电子邮件通知设置。
为什么没有我对系统进行任何更新，特定man页面（在我的情况下，对于nc命令）会有今天的日期？另外，为什么“无人值守更新”日志没有显示当天的任何特定活动？
