Unfortunately, Stellarium does not work with the last OS version of Sailfish. I contacted the developer and he said that he doesn't use the Jolla anymore (he uses the N9 instead). He was disappointed by Jolla mostly due to the company's attitude toward native app development. Sad He also said that if there is interest and the change is trivial, or someone contributes patches, he might update it. So if someone is willing (and capable) to help, he is warmly welcome!
