I resolve this install kernel dependencies, like this:

apt-get -y install linux-image-generic
apt-get -y install linux-headers-generic
apt-get -y install linux-image-extra-`uname -r`

After that we need to add the quota modules to start with boot:

echo quota_v1 >> /etc/modules
echo quota_v2 >> /etc/modules

reboot

Check if it’s working:

sudo -s
cat /proc/modules | grep -i quota

quota_v1 16384 0 - Live 0xffffffffc037c000
quota_v2 16384 2 - Live 0xffffffffc0377000
quota_tree 20480 1 quota_v2, Live 0xffffffffc0250000

quotaon -pa

group quota on / (/dev/sda1) is on
user quota on / (/dev/sda1) is on

Hi @msanchezdbc0b60dea889885dd

Did you edit the /etc/fstab and add the usrquota and/or grpquota ?
When you ran the mount -o remount / did it successfully remount ?

Yes:
