--- Comment #5 from Rosanne DiMesio dimesio@earthlink.net --- The WineHQ repository structure has been changed to sync with the OBS, which uses a flat repository structure rather than a Debian-style one. That's why you got those messages about accepting changes. So no, we cannot go back to a strict Debian-style structure.
The good news for you is that you can get your Testing packages directly from the OBS repository, which is set up as a rolling release.
Just download and install the OBS release key (https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/Debian_Te...) and add the repository to your /etc/apt/sources.list: https://download.opensuse.org/repositories/Emulators:/Wine:/Debian/Debian_Te... ./
Note the ./ at the end; that's needed because of the flat structure.
Note also that the OBS only has the latest packages, so if you ever have to downgrade for some reason, you will have to get the old package from the archive here.
