Hi, I've also fixed the issue for the suspend feature and lightdm feature by removing packages libpam-modules:i386 and libpam-cap:i386, which have the same kind of conflict as explained above. I don't know what happened during the upgrade, but it looks like the upgrade tool was a bit lost between i386 and amd64 packages.
