Following the guide, I have tried at both SF and NYC regions with ubuntu 16.04 and cannot get past installing docker without first following the recommendations from this old topic.
sudo apt-get install lxc wget bsdtar curl
sudo apt-get install linux-image-extra-$(uname -r)
sudo modprobe aufs
Either I am doing something odd or the guide needs updating yeah?
The first command of the guide(wget -qO- https://get.docker.com/ | sh) already install aufs for you if you are using a compatible server.
Well, what I am saying here is that is not what is occurring on a fresh DO ubuntu installation. I have tried with both 16.04 and 16.10. The command wget -qO- https://get.docker.com/ | sh doesn’t run successfully. This is what I am seeing:
root@ubuntu:~# wget -qO- https://get.docker.com/ | sh
modprobe: FATAL: Module aufs not found in directory /lib/modules/4.4.0-57-generic
It continues doing its thing but is non functional at the end and so ultimately the discourse install is unable to bootstrap.
Are you deviating from our official guide in any way? Are you selecting some kind of wacky pre-built droplet, or a clean Ubuntu Server 16? Because @pfaffman and I have installed dozens of times following that guide step by step on Ubuntu 16.04 LTS server droplets and we had zero issues.
I just did it a moment ago. Exactly these steps:
wget -qO- https://get.docker.com/ | sh
modprobe: FATAL: etc…Could it be datacenter specific?
I can try to repro later. Out with the family at the moment.
I’m also getting this error.
Does following the steps in this topic help?
Yes, but you have to do them before you ever try to install docker. The same ones I mention at the beginning of this topic.
So I just tried again on a fresh local virtual box VM of ubuntu 16.04.1 x64 and I didn’t get the error:
It looks like you are reporting something as an error that’s not really an error?
I just set up Discourse on a new SFO 2GB Ubuntu 16.04 LTS droplet. I do see the “error” but it just scrolls on by and everything works fine – Docker seems plenty happy, note aufs is there:

After bootstrapping it loads Discourse just fine, following the official install guide, step by step, no deviations.
I will try to reproduce further then/again.
Oh dear. I really cannot get it to fail now (that FATAL: Module aufs not found is still there but everything else works as it is supposed to). I was so convinced Iit was a problem further down the line. Very sorry guys and thanks for all your help!
