OMG, IT WORKED
I am the happiest guy in the World for 5 minutes.
This is the solution that I found for aws ec2 servers
Changing the kernel boot parameters on AWS for the official Ubuntu images is just as simple as editing /etc/default/grub.d/50-cloudimg-settings.cfg in the same way you’d usually edit /etc/default/grub. Note that you have to run ‘update-grub’ afterwards and then reboot.

$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.4.0-1041-aws root=UUID=512611f4-b05a-4d8a-b743-438b71c5385d ro console=tty1 console=ttyS0
yes, I am on aws. This system started to getting hard to me.

Can you show the output of 'cat /proc/cmdline'? It should contain "cgroup_enable=memory swapaccount=1".
From previous lines I think I saw you're running on AWS, and there you may need a different way to change the kernel boot parameters, but I don't know exactly how. Maybe someone else can step in, or you'd have to search the AWS documentation for how to do so.

It looks like you missed the command sudo groupadd domjudge-run under https://www.domjudge.org/docs/admin-manual-3.html#ss3.7 <https://www.domjudge.org/docs/admin-manual-3.html#ss3.7%3E. Does that help?
