I was also coming from stock ROM KRT16O.
If you download the rom using windows, try to open the zip file first. If the zip won't open, the file you are download are corrupt and I think you have to download it from another source. I always dont this before flashing a new rom.
After that, I usually delete or format data, system, cache and dalvik in TWRP. Dont't forget to delete cache and dalvik after your installation success then reboot..
That step always working find for me..

all I can suggest is download, use the latest recovery, and flash.. I have heard that people have better luck with my Google drive link, so try that

Well, I downloaded first time from Google Drive, it failed. All zip files I downloaded were able to be opened. I am using twrp 188.8.131.52. I think it's not so different with 184.108.40.206 but I'll check it again.
Btw, the flashing process was unable to run at all. The error message is in my post on earlier page. I'll test one more time and report back.
