Comment 1 for bug 161783

I can confirm this.

Here's the output from $ sudo apt-get install ubuntu-xen-desktop:

---------------------------------------------------

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  ubuntu-xen-desktop: Depends: libc6-xen but it is not going to be installed
E: Broken packages

---------------------------------------------------

And here's the output from $ sudo apt-get install libc6-xen:

And finally, here's my recent apt-get install activity from .bash_history. As you can see, I flailed around a while trying to find the right packages to install:

--------------------------------------------

sudo apt-get install xen-utils-common
sudo apt-get install xen-hypervisor
sudo apt-get install xen-shell
sudo apt-get install xen-tools
sudo apt-get install xen-utils-3.1
sudo apt-get install xen-image-2.6.19-4-generic
sudo apt-get install xen-hypervisor-3.1
sudo apt-get install linux-restricted-modules-xen
sudo apt-get install xen-ioemu-3.1
sudo apt-get install xen-ioemu
sudo apt-get install ubuntu-xen-desktop
sudo apt-get -f install

---------------------------------------

I've managed to somewhat boot from the xen kernel, but X was broken, as was a lot of other stuff, I don't remember it all. I just rebooted into my old kernel (2.6.22-14) immediately.
