I am running Ubuntu 15.04 and wanted to upgrade it to 15.10. While getting the packages information, the upgrade process stopped with the mentioned error.

Looking at the contents of file VarLogDistupgradeAptlog.txt, I think it might be related to Wine. The last few Ubuntu versions, anytime when I install Wine on a 64-bit installation, I always have to upgrade Wine on the command line. If I use the graphical updater, Wine packages are never upgraded because of missing i386 dependancies. The following CLI commands do find those dependancies, allowing Wine to be updated.

sudo apt-get update &&
sudo apt-get upgrade

Perhaps this issue is now withholding the upgrade from proceeding.
