I've had a series of unsuccessful attempts at installing MemSQL 6.8.5 on my Ubuntu 18.04.2 LTS machine. The bottomline is I'm unable to fully install this software since MemSQL claims I already have nodes installed preventing an install. When I attempt to view the MemSQL nodes I have installed, MemSQL returns 'no nodes found.'

Would anyone happen to have an idea how to resolve this issue?

Example:
========

**prompt#: memsql-deploy cluster-in-a-box --license [license]**
