Problem:

I cannont install vmware mui after upgraring to eft 6.10, it says that it cannot start the server. Here is the sum of solutions you have to do. 

 1) Change sh to bash

sudo rm -f /bin/sh
sudo ln -s /bin/bash /bin/sh 

2) remove libdbus-1-2 since it has been left behind when upgrading. from dapper to eft.

3) Reinstall MUI, and 1-2-3 everything works.
