I like hearing that the problem is something as (relatively) trivial to solve as this. I know carrying more fuel with the rocket isn't exactly an easy thing to do, but far easier than finding out there's something fundamentally wrong with the design. SpaceX is amazing and I'm glad they're doing the hard stuff.

It apparently ran out of TEA-TEB ignition fluid, not fuel:

I can't find any info on how much TEA-TEB is carried on-board, only that it's ground supplied for initial launch with the on-board TEA-TEB being used only for restarts.

(I'm not even an amateur rocket scientist: I just googled all this.)

Has anyone seen any updates on how their fairing recovery attempt went? They had the ship done and seemingly ready back in December - https://imgur.com/gallery/MQcEE

Fairing recovery was asked in the press conference afterward - here's a transcription from r/spacex

Fairing recovery has proven surprisingly difficult. I'm still fairly sure we can do it in the next six months, but the fairing is [not aerodynamic], messes with the parachute... we also have a fairing version 2, much more important than version 1 fairings.... my guess is next six months for fairing recovery. We have the special boat. .....we might even be able to catch the dragon too, if nasa wants to

Will it work, though? Is the center-core restart happening under the same conditions as the heretofore successful ones? Is it really a matter of adding more lighter fluid? (That's like The Cable Guy's BBQ advice.) How fast is the wind those rocket nozzles are pointed into?

I bet it didn't randomly lack fluid due to some stupid miscalculation. It's probably more like: "Due to unforeseen circumstances it needed more fluid than expected. But we adjust our numbers and next time we expect more (in the hopes that it will be enough, which it will probably be)."

Isn't the fairing just a simple pair of metal casings. Why bother to recover it?
