I have been trying for months to get help setting up their new version of AMS. The instructions from their own github are incomplete and I have yet to receive a single answer in their official IRC support channel.
Pretty much the same problem I ran into. There's some crucial steps missing from the GitHub. Might be completely different if you're an experienced linux user but my knowledge is limited. I emailed Steven in early Dec, he forwarded my email to
shibin@canaan-creative.com but never heard back from anyone.
