如何获取AWS内核上的配额内核模块？

我似乎无法安装 Ubuntu 16.04 AWS 内核的配额模块。我已经启动了官方云映像（ami-e5d9439a来自Ubuntu 的云图像网站）。检查内核模块显示它们没有安装：

ubuntu@ip-10-0-0-78:~$ modprobe quota_v1
modprobe: FATAL: Module quota_v1 not found in directory /lib/modules/4.4.0-1060-aws
ubuntu@ip-10-0-0-78:~$ modprobe quota_v2
modprobe: FATAL: Module quota_v2 not found in directory /lib/modules/4.4.0-1060-aws

获取配额模块的常规技巧是安装内核的 linux-image-extra 包，但这个包不存在：

ubuntu@ip-10-0-0-78:~$ sudo apt-get update
...
ubuntu@ip-10-0-0-78:~$ sudo apt-get -y install linux-image-extra-`uname -r`

E: Couldn't find any package by glob 'linux-image-extra-4.4.0-1060-aws'
E: Couldn't find any package by regex 'linux-image-extra-4.4.0-1060-aws'

linux-image-extra-virtual当然，安装没有帮助，因为它安装的所有内容都是错误的内核版本：

ubuntu@ip-10-0-0-78:~$ sudo apt-get install linux-image-extra-virtual

是否有可以安装的软件包来获取配额内核模块？或者，如果我想在 AWS 机器上使用磁盘配额，是否必须自行构建它们？

长话短说：安装linux-modules-extra-aws包。

我花了很多时间在这个问题上，答案却隐藏在问题本身的评论中。

启动板上有一个关于此问题的错误报告bugs.launchpad.net/ubuntu/+source/linux-aws/+bug/1773172— MrSpock 2019 年 3 月 12 日 14:12

希望这也能帮助其他人。
