How to install Neo4j on Ubuntu 16.04?

I can't get the Neo4j service to start on Ubuntu 16.04. A while ago I was running a Ubuntu 14 and I was able to install Neo4j just fine. But then I removed it and time passed and I've upgraded to Ubuntu 16 and now I want to check out Neo4j again and it's not installing. I have java and anything it asks me. I'm little aware that that Ubuntu changed the service launcher and I think that might be it but I don't know enough in either Ubuntu or Neo4j to know where to start debugging to figure out how to make this work.

Can someone point me to logs to look at or can they fill in any holes in my knowledge to help me?

I figured it out! I had to allow non-local access to Neo4j.

In the previous versions of Neo4j, the default installation would allow remote connections. Since I've always installed this on a headless server, I just assumed this was how it is. In the new Neo4j 3.0, this is turned off by default and you have to go into neo4j.config and uncomment the appropriate lines in the networking section to allow connections. Made the config changes and reboot the machine just for good measure and everything started to work.
