Popis: We characterize the solvable Lie groups of the form $${\mathbb {R}}^m\rtimes {\mathbb {R}}$$ , whose $$C^*$$ -algebras are quasidiagonal. Using this result, we determine the connected simply connected solvable Lie groups of type I whose $$C^*$$ -algebras are strongly quasidiagonal. As a by-product, we give also examples of amenable Lie groups with non-quasidiagonal $$C^*$$ -algebras.
