There are three negative points in the English Grammar Profile at C2 Modality that are quite rare.

Point 215 is defined as:

negative form ‘ought not to’

Point 226:

CONTRACTED NEGATIVE ‘oughtn’t’ (without ‘to’) + verb

Point 235

‘ought’ + subject + ‘not to’ + verb to form (rhetorical) questions, often in formal contexts.

*Point 35 in the category of QUESTIONS yes/no is also C2 with uncontracted ‘not’ to emphasise a point in an argument.

However, there is no allowance in the EGP for a question using ‘ought’ that is not negative.  We will then refer to another source: Pearson’s GSE 62 B2 

‘ought(n’t) to’ to offer or ask for advice or suggestions.
