Let be an integer, , be distinct odd primes. Let , be two groups of order with their Sylow--subgroups being cyclic. We enumerate the Hopf-Galois structures on a Galois -extension, with type . This also computes the number of skew braces with additive group isomorphic to and multiplicative group isomorphic to . Further when , we give a complete classification of the Hopf-Galois structures on Galois--extensions.
