Hey @jopasserat I think I found the reason this doesn't work. I tested this on a t3a.2xlarge machine on AWS and it also broke for me. It works every else though. I looked into this instance and it looks like the t3a.2xlarge uses an AMD processor. While a goal of asylo is to be agnostic to CPUs and enclaves I think right now they leverage Intel's SDKs quite a bit. Like they are just using Intel's SGX Simulator and only support Intel SGX. Assuming the simulator doesn't work on AMD CPUs. I'd recommend using t3.2xlarge.

Is this a requirement to have SGX even for the simulation mode?
It's intended to run locally without an SGX device. So this is definitely a bug

Yeah. You shouldn't need a machine with sgx to be able run in simulation mode. Can you give us some more information about your environment? Linux vs macos, etc. And anything else you can think of. Those error messages aren't very helpful so any more info you can provide will help us solve the problem. Thanks!

I'm working on a AWS VM (t3a.2xlarge) running Ubuntu 18.04 with docker 18.09
(base) ubuntu@ip-XX-XX:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.2 LTS
Release: 18.04
Codename: bionic
(base) ubuntu@ip-XX-XX:~$ docker --version
Docker version 18.09.6, build 481bc77
Nothing installed on the machine apart from that and working from a tf-trusted clone up to date with the current master branch.
Any steps I should run to provide you with more information?

Thanks for this. The first thing that comes to mind is I'm not sure I've run this on Ubuntu 18.04. Maybe only 16.04. If you want to try on a fresh 16.04 that'd be great and I can try on 18.04 when I get back on Monday.
Another thing is I've usually run on GCP not AWS. Shouldn't matter but you never know.

Same on Ubuntu 16.04, would have been crazy since all the build happens in docker.
A bit more context around the error:

More info: it seems that the issue comes from Asylo directly, I've tried to run their quickstart on the same machine => same error. Full stacktrace below:

Yeah good point about it running in docker. This is a long shot but wonder
if it could be related to this latest commit
