Fantastic, comprehensive tutorial, but I am banging my head against the wall the past two days.

I have a 22 vCPU Intel Haswell VM running Ubuntu 16.04 LTS(amd64 xenial image). I already have wifkey from my user acct, so I dont generate one w/ "suggest_brain_key" I use the active private key from my account (I have actually tried both my active key and the key spit out by "suggest_brain_key"); however, this may have nothing to do with why I have a concussion from banging my head against the fuc&(ng wall.

When its show time and I enter the ./steemd --rpc-endpoint --seed-node="seed.steemed.net:2001" command or the ./steemd --rpc-endpoint command, I am hit with the following:

maybe_found != nullptr: Unable to find Object
    {"id":"2.20.0"}
    th_a  index.hpp:111 get

Before I lose consciensness, could someone please just point me in the right direction. I realize it has to do with the graphene /db/index.hpp. But I cannot figure out what object "id" :"2.20.0" refers to. The first person who can get my VM up and mining will receive 10% of the gross amount mined by that machine over a 5 day period of the geniuses choosing. So, HELP ME, HELP YOU, HELP ME TO HELP YOURSELF! Thanks in advance, I do appreciate it! Feel free to contact me via the e-mail address listed below.
