I was trying to upgrade to quantal via 'do-release-upgrade -d' and encountered the following:

Preparing to replace dpkg 1.16.1.2ubuntu7 (using .../dpkg_1.16.3ubuntu1_amd64.deb) ...

As far as I can tell a recovery was not run and when trying to run it manually I received a dpkg error:

dpkg: error: file triggers record mentions illegal package name `libgtk2.0-0' (for interest in file `/usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/immodules'): ambiguous package name 'libgtk2.0-0' with more than one installed instance
