Sharik987, about the interface - this is the standard field that needs to be filled when the program is laid out. And yes, the program, in general, does not necessarily have an interface. The concept of a repository can be extended indefinitely, but in this case these are mirrors of NOKIA DEVELOPMENT repositories from which you can download some system packages, such as developer mode and a number of other system packages, including operating system components. The store is a separate topic, those repositories there was no way to mirror, so WareHouse appeared.
