Hi, I m trying to install the Sugar development environment on my laptop which has Ubuntu6.10 installed on it.  Upon issuing the command: <a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:sugar@laptop.org"> </a>sudo apt-get install build-essential cvs docbook-utils subversion libgtk2.0-dev libidl-dev    gnome-common gtk-doc-tools libxt-dev automake1.7 automake1.8 automake1.9 python-gtk2-dev    python-avahi git-core cogito python-dev avahi-utils    libgconf2-dev xserver-xephyr libgnome2-dev libmatchbox-dev python-cairo-dev    libtiff4-dev python-gnome2-dev libxdamage-dev libxdamage1 libxcomposite-dev    libgnomeui-dev libtool libfribidi-dev libgsf-1-dev libbz2-dev libwmf-dev    libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libgnomeprintui2.2-dev    libenchant-dev libnspr-dev darcs libxslt1.1 libxslt1-dev firefox firefox-dev    libasound2-dev as given on the <a href="http://wiki.laptop.org/go/Sugar_on_Ubuntu_Linux"> http://wiki.laptop.org/go/Sugar_on_Ubuntu_Linux</a> website, I get a message, the last part of which I have pasted here: Get:21 <a href="http://security.ubuntu.com">http://security.ubuntu.com</a> edgy-security/universe xserver-xephyr 1: 1.1.1-0ubuntu12.1 [1499kB] Media change: please insert the disc labeled                           'Ubuntu 6.10 _Edgy Eft_ - Release i386 (20061025)' in the drive '/cdrom/' and press enter I have enabled the Universe and Multiuniverse repositories on my machine.
