For the main repositories (fedora-debug-28 and fedora-modular-debug-28) and the update repositories (updates-testing/released*debug-f28) the paths a very inconsistent and make it difficult for MirrorManager to guess which is the right repository.

For the updates repository there was repodata directory at debug/repodata and debug/tree/repodata. As MirrorManager uses the existence of a repodata directory as a hint that it might be a repository it needs to handle, it is based on which directory it detects first, which one becomes the repository.

There were also problems for the main debug repositories because of the 'tree/' subdirectory.

It would be good if future releases could be pushed without the 'tree/' subdirectory for all new repositories to make it consistent and easier to handle.
