我尝试升级两个独立的 Ubuntu 系统以包含最新的崩溃补丁，但没有成功。
这是我所做的：
$ sudo apt-get update && sudo apt-get dist-upgrade
$ reboot
$ uname -r
4.4.0-42-generic
本文https://usn.ubuntu.com/usn/usn-3522-1/似乎表明16.04有一个解决方案，安装方法是使用上面的说明。
我错过了什么？
编辑1：
运行成功后
sudo apt install linux-generic
内核还是一样
$ uname -r
4.4.0-42-generic
因此我按照 David 的要求运行了以下命令
$ apt-cache policy linux-generic linux-image-generic 'linux-image-4\.4\.0-.*-generic'

答案1
现在您的内核已经有了一个很好的补丁，请执行以下操作：
sudo apt install linux-generic
这将强制您升级内核。
