Comment 14 for bug 571999

The install log in this bug says:

dpkg: regarding .../wine1.2_1.1.42-0ubuntu4_amd64.deb containing wine1.2:
 wine1.2 conflicts with wine (<< 1.2)

debian/control for the current Lucid package says:

Package: wine1.2

Replaces: wine (<< 1.1.36-0ubuntu2), wine1.0, winesetuptk, wine-doc, wine-utils, libwine-alsa, libwine-arts, libwine-capi, libwine-cms, libwine-esd, libwine-gl, libwine-gphoto2, libwine-jack,
libwine-ldap, libwine-nas, libwine-print, libwine-sane, libwine-twain, xwine, ttf-tahoma-replacement

So it looks to me like this upgrade was done off of a stale mirror. I can't replicate this with the final package.
