I started the trip in ZZZ the crew that brought Aircraft X in had a fume event on descent at 3;000 ft.; it was determined by Maintenance that the problem was with Pack 1 so; Pack 1 was deactivated; during boarding we smelled it again with Pack 2 running and APU; Maintenance was called and the APU was deactivated.During descent through FL 210 we smelled it again with both engines running; both bleeds open; Pack 1 off; APU off; Pack 2 on.
A320 Captain reported a fumes event during boarding and also during descent at destination.
