Let G be a finite group such that \(\mathop {{\text {SL}}}\nolimits (n,q)\subseteq G \subseteq \mathop {{\text {GL}}}\nolimits (n,q)\) and Z be a central subgroup of G. In this paper we determine the group T(G / Z) consisting of the equivalence classes of endotrivial k(G / Z)-modules where k is an algebraically closed field of characteristic p such that p does not divide q. The results in this paper complete the classification of endotrivial modules for all finite groups of (untwisted) Lie type A, initiated earlier by the authors. Jon F.
