The current Debian archive as provided by WineHQ appears not to work. The
following error has started appearing as of sometime late 10/Apr/2018:

E: Failed to fetch http://wine.delta/dists/buster/main/binary-amd64/Packages.xz
 File has unexpected size (20632 != 3336). Mirror sync in progress? [IP:

Do you want to accept these changes and continue updating from this repository?
[y/N]

I am fairly confident this is not simply a user-end misconfiguration. There are
two others posting of the same problem on the WineHQ forum; I apologise if
they've filed a bug, I couldn't find one.
