Error CL_PLATFORM_NOT_FOUND_KHR in running HashCat 5.1.0

Following up from this post,

I have followed these instructions, including other resources. Here is the error:

dan@dans-ubuntu:~$ hashcat -I

Attempts to resolve:

0. Following the answers from this post
1. Easy install with apt install intel-opencl-icd
2. Manual install found here

I have fixed the issue. While hashcat will not run on my intel integrated graphics, it will run on my GPU. I had to install the nVidia cuda development kit found here. This solved everything.
