Actually that was the problem there is no error message, after it install Kubuntu and reboot, now you need to do the update & dist-upgrade, here you get "Zero packages to update", then you double click LinuxMCE icon on the desktop, then it will take few minutes instead the normal ~30 minutes, and it will shows it is DONE and ask you to reboot, after reboot you get the terminal login prompt instead of the AV Wizard.
So after installing Kubuntu you need to apply the fix then do "apt-get update" "apt-get dist-upgrade" if it ask you at the end to run it with -f switch then do "apt-get -f dist-upgrade" then you double click the "LinuxMCE icon" and you should be all set.
