Comment 8 for bug 1460868

I'm adding the unity8-desktop-session package to this bug report since this is where RAOF says we need to add a dependency. This won't fix Daniel's use case in the bug description since he is just trying the mir_demo_server on a desktop.

At any rate, anyone using the unity8-desktop-session-mir package will have the correct packages installed once the "fix" goes in.
