Comment 6 for bug 1436834

Ok, I'm thinking that this is a change Ubuntu has made to the package-data-downloader (I test on 12.04 and 14.04), could you please try editing the file "/usr/share/wine-browser-installer/install-files" and removing the part that says:
----
# Remove all the temporary files
for tempfile in "$@"; do
 rm $tempfile;
done
----
and then trying the download again?
