How to enable domains disk quotas monitoring?

I reinstalled on new server 16.04 and cant find it.

In Webmin->System->Disk quotas i have Filesystem /

/ New Linux Native Filesystem Partition labelled DOROOT User and group quotas inactive Enable quotas

and pressing Enable quotas gives error

Failed to turn on quotas : quotaon: using //aquota.user on /dev/vda1 [/]: No such process quotaon: Quota format not supported in kernel.

This problem is also in here

Turns out; this may be related to the fact that some of the quota kernel modules are not included in the Ubuntu AMI image. In my case, I’m using 16.04.

Some people noted installing the linux-image-extra-virtual modules fixed their issues.

apt-get install linux-image-extra-virtual

This was not the case for me. I found that kernel support was then enabled, but module files were still missing. It was at this point; this is just a waste of my time.

modprobe quota_v1 or modprobe quota_v2 returned error; modprobe: FATAL: Module quota_v2 not found in directory /lib/modules/4.4.0-1016-aws

A quick check on one of my Debian images indicates that the quota modules are built in by default. Note, however; that there are other restrictions with Debian - such as no php7 without enabling testing.
