>From http://forum.ubuntu-fr.org/viewtopic.php?id=914271 . It does help, when you first boot as live CD and then remove ubiquity-slideshow-(xubuntu) packadge. you can do it from live session bu opening terminal and typing there: sudo apt-get remove ubiquity-slideshow-xubuntu. Instead of "xubuntu" use your distro name.
I did this on Lubuntu 12.04 and then started the installation from desktop icon and this time it went smoothly. ** Also affects: ubiquity-slideshow-ubuntu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989968 Title: **CRITICAL** Unable to create '/root/cache/dconf'; dconf will not work properly.
