how do you do get

[Blue Apple]

Hi there. In this BBC News article I encounter the following sentence. Can anybody explain the structure "how do you do get" to me?

Sentence:
But how do you do get a computer program to avoid churning out a useless maze with too many walls, or an otherwise impenetrable floorplan?

It's a mistake.
But how do you do get ... ?

Agreed - it is a simple error.
