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 的云映像站点）。检查内核模块显示它们尚未安装：
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
获取配额模块的正常技巧是为您的内核安装 linux-image-extra 软件包，但此软件包不存在：
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`
