Thank you for that cache code to get the proper install file names. Had no idea these addons were done that way in Linux. 

For future reference for other newbies wanting to install these two addons, here are the steps:

Close Kodi
Open Terminal
Run these two commands:
sudo apt-get install kodi-inputstream-adaptive

sudo apt-get install kodi-inputstream-rtmp
 
Open Kodi
go to Add-ons/My add-ons/VideoPlayer InputStream/ 
Enable InputStream Adaptive
Enable RTMP Input

These instructions will be required for Linux Mint apparently because they are not added to the original install for Kodi. Hope this helps others as it fixed everything for me. Turning off auto update for now to be sure lol.
