Jan 26, 2022 at 19:32 comment added Salvo Tringali @NameNo Are you implicitly referring to [G. Marks, Duo rings and Ore extensions, J. Algebra 280 (2004) 463–471] when you write that skew polynomial rings "don't give duo examples for the weakened version" of my problem"?
Jan 26, 2022 at 9:18 comment added NameNo Only a weak attempt to keep alive algebra on mathoverflow. Henriksen's problem and yours can be weakened using algebras where all inverible elements are scalars (algebras over the field with two elements give the original problem). Cohn's method for the commutative case works in this setting (extending to an algebra where each non-zero divisor is a scalar). Skew polinomial rings don't give duo examples for the weakened version of your problem, but skew power series rings might (only over a field with nonidentity auto/endo/morphism).
