Installer crashes while trying to install packages from CD

[Prateek Karandikar]

Binary package hint: ubiquity

I was installing Ubuntu 10.10 from a USB disk created by Ubuntu's usb-creator from ubuntu-10.10-desktop-i386.iso. The installer aborted "while trying to install additional packages from the CD" (I don't remember the exact wording). It explicitly instructed me to file a new bug, and not to attach details to an existing bug.
