Ditto, on the reminder to triple-check your tires to ensure there isn't some existing thorn, glass or other such thing embedded in there, working its way into every tube you try.

Both Schwalbe and Continental, for example, have some models of tires that have a very tough 3mm or 5mm anti-puncture piece integrated into the tire's construction.
I've used the Conti Ride Tour tires with exceptional results in a high-risk urban setting with plenty of road hazards ... no flats in several years on them.
If I were looking for max puncture protection on urban streets, I'd consider one of the following tires. These are three in the 55-584 or 50-584 sizing:
Continental Contact Plus City, 55-584 ETRTO (27.5"):

Schwalbe Marathon e-Plus, 50-584 ETRTO (27.5"):
