I tried to install Gala window manager (the windows manager of Elementary OS) on Xubuntu 14.04 as described for example here, but seems like there is an unmet dependency. The error is

The following packages have unmet dependencies:
gala : Depends: libmutter0d  3.12.2-1ubuntu99~elementary0.3.4) but it is not installable
E: Unable to correct problems, you have held broken packages.

I also installed the libmutter0d package but the error persists. Is there something I can do to get through this?

Since the beta1 of the new version of Elementary (based on ubuntu 14.04) is testable, another option would be installing the beta version of gala. I'm not sure if it is possible, but is yes, what are the necessary step to do so?

No solutions found there. Gala seems to be installable in Ubuntu versions 13.10 downward only. – user47224 Aug 16 '14 at 13:15

solved it with

sudo apt-add-repository ppa:elementary-os/testing
sudo apt-get update

then the right version of libmutter0d is there

In this way Gala can be installed, but if I launch it two errors appear and it crashes: "libGL error: failed to authenticate magic 1" and "libGL error: failed to load driver: vboxvideo" . I don't know if they are related to the virtualbox session only, or the package doesn't work properly. – user47224 Aug 16 '14 at 19:10
@user47224 I suspect that problem is not related to the original difficulty installing it. You might want to post a separate question to ask about that. – Eliah Kagan Aug 18 '14 at 0:12
