Ubuntu 11.04 installer crashed while configuring apt

[Sasha Gerrand]

Binary package hint: ubiquity

While installing Ubuntu 11.04 from a USB flash drive, the installation process crashed while attempting to configure the apt sources. The install was on a freshly formatted HDD.

The error message returned from apt was: "An attempt to configure apt to install additional packages from the CD failed."

The installer then crashes. Subsequent attempts to install have all failed thus far.
