For anybody attempting to do this on a Raspberry Pi on Raspbian (Stretch), you need to install mlocate first.
Looking at the install script, I would have thought that with this missing it would just attempt to install the dependencies anyway, and it did launch a window in which to do so but it didn't seem to do anything. No big deal, just install mlocate and, for good measure, the dependencies first, then run install script and it all works beautifully!
Thanks for the work and support on this project!
