Thanks for helping me identify me initial error :)
Current output of: cat /etc/apt/sources.list.d/ring-nightly-main.list
deb https://dl.ring.cx/ring-nightly/ubuntu_16.04/ ring main
However, after a number of tries, I noticed I keep getting this error:

Then, just on a hunch, I tried it again without the --fix-missing ... and now
it's installed!
