JupyterHub not launching with AWS #654

Bug description

I'm trying to get The Littlest JupyterHub set up through Amazon Web Services by following this tutorial, but it looks like it's getting stuck at "Downloading & setting up user environment..." and never making it to the "Setting up JupyterHub..." step. I was just wondering if anyone has a recommendation about how to troubleshoot from here.

I got stuck at the same point in the log! I rebooted the instance and when I checked the system log on reboot, apparently the instance ran out of memory and didn't bother letting me know. My best guess is that something about the install package's RAM consumption changed since the tutorial was written--that, or the t2.micro tier's available RAM changed.

This issue should have been addressed now by fixing memory issues in various ways. #697 was one of the ways and I think I've linked to that issue from the other memory related issues, so search its mentions to track those down if you want to dig in deeper.
