Ubuntu 16.04を更新してメルトダウンとスペクターパッチを含める方法

2つの別個のUbuntuシステムをアップグレードして、最新のメルトダウンパッチを使用できないようにしようとしました。

ここに私がやったことがあります：

$ Sudo apt-get update && Sudo apt-get dist-upgrade
$ reboot 
$ uname -r
4.4.0-42-generic

この記事 https://usn.ubuntu.com/usn/usn-3522-1/ は、16.04の解決策があることを示唆しているようで、そのインストール方法は上記の手順を使用することです。

私は何が欠けていますか？

EDIT1：

正常に実行した後

Sudo apt install linux-generic

カーネルはまだ同じです

$ uname -r
4.4.0-42-generic

だから私はデビッドの要求に従って次を実行しました

$ apt-cache policy linux-generic linux-image-generic 'linux-image-4\.4\.0-.*-generic'

カーネルに適したパッチが利用可能になったので、

Sudo apt install linux-generic

これにより、カーネルが強制的にアップグレードされます。
