Sprinkle salt over the ribs. If needed cut the ribs into smaller pieces to fit in the Instant Pot®. Set aside while continuing with the rest of the prepping.
Place the dried chilies, cumin seeds, cloves, cinnamon stick, Kashmiri red chili powder, and turmeric in a spice mill or coffee grinder and grind to a powder.
Set the Instant Pot® to Sauté mode, and heat the oil for about 1 minute. Add the red onion, garlic, and ginger and sauté for about 2 minutes. Stir in the ground spice mixture and vinegar. Add the ribs and cook, stirring, until the ribs are coated and the mixture is a rich reddish-brown color, about 3 minutes. Add the chicken or vegetable broth and brown sugar and stir well. Bring the mixture to a simmer.
Press Cancel to turn off the Sauté mode. Close the lid and set the Instant Pot® on the Meat/Stew mode for 25 minutes.
When cooking time is complete, allow for Natural Pressure Release for 10 minutes, then use Quick Release for any residual pressure.
Once the pressure is released, open the lid and set the Instant Pot® to Sauté mode and simmer to thicken the liquid. Drain off any excess fat.
Garnish with the green onions and crushed red pepper and serve with steamed rice or crusty bread.
