MongoDB Failing to Start - ***aborting after fassert() failure

Question

I am new to Ubuntu (Linux tbh). I encountered problem with starting MongoDB service. I want to created web app using Ruby on Rails and MongoDB but mongo seems to fail to start.

I followed this MongoDB installation on Ubuntu all of installation went without problems until I got to sudo service mongod start

mongod.log

Does the file /tmp/mongodb-27017.sock exist? If so try to delete it, ie. 'sudo rm /tmp/mongodb-27017.sock'.
