This ofcourse doesn't mean there's no problem though. Personally I have many packages installed from experimental and even some not yet uploaded. I'm guessing mfv might have updated some package as well to make it work for him. I think there's a good chance thus that gnome-maps simply misses a (versioned) dependency somewhere to guarantee another component is upgraded when gnome-maps is. If you could please look at the dependencies of gnome-maps and check if there's a package in experimental you can upgrade too, do each upgrade separately and test gnome-maps at each step, likely you'll then find the culprit and we've identified the missing dependency. Your help would be very welcome. Regards, Andreas Henriksson
