I cannot start the Neo4j service on Ubuntu 16.04. Some time ago I was running Ubuntu 14, and I was able to install Neo4j just fine. But then I deleted it, and the time passed, and I upgraded to Ubuntu 16, and now I want to check Neo4j again and not install. I have java and all that he asks. I know little that Ubuntu has changed the service launcher, and I think it could be so, but I don't know enough in either Ubuntu or Neo4j to find out where to start debugging, to figure out how to do it.
Can someone point me to the magazines to watch or can they fill all my knowledge to help me?
