--- Comment #1 from Rosanne DiMesio dimesio@earthlink.net --- Syncing takes time. There is nothing we can do about that; if you get the "mirror sync in progress?" message just wait awhile and try later. We have a sticky on the forum telling users exactly that: https://forum.winehq.org/viewtopic.php?f=8&t=31878.
Syncing is complete for 4.8; I had no problem installing it in bionic.
