I'm running hardy heron on an XPS M1710.

My update manager is telling me that I have new update to install:

When I click install updates I get the following error:

E: /var/cache/apt/archives/gnome-do-plugins_0.5.98.0-0~hardy~ppa2_all.deb: trying to overwrite `/usr/share/gnome-do/plugins/Rhythmbox.dll', which is also in package gnome-do-plugin-rhythmbox

I would really appreciate any help that you can provide. Thank you in advance.
