Title:
  An attempt to configure apt to install additional packages from the CD
  failed upon install from USB

Status in “ubiquity” package in Ubuntu:
  Triaged
Status in Baltix GNU/Linux:
  New

Bug description:
  Binary package hint: ubiquity

  Description of problem:
  When trying to install Ubuntu 10.10 from USB, ubiquity crashes with this message: "An attempt to configure apt to install additional packages from the CD failed."

  Root of problem:
  The problem is that the file structure on the usb differs to what is on a livecd and apt-setup is unaware of this.

  WORKAROUND:

  There appear to be two alternatives:

  a) Remove the script that causes the error, when installing from a Live setup ("Try Ubuntu"):
     sudo rm /usr/lib/ubiquity/apt-setup/generators/40cdrom

  b) Create the files as they are expected:

     To resolve this, simply copy the contents of filesystem.squashfs on the iso into the usb stick. Luckily the parts it is reading from this appear to be just apt config files so the fact that you lose symbolic links or permissions on a FAT32 usb stick shouldn't matter.
     
     On your current Linux installation: (If you don't have one you could use a live cd off a different usb stick)
     1. Create USB stick.
     2. Type in a terminal:
     sudo mkdir iso
     sudo mkdir source
     sudo mount -o loop pathtoiso/ubuntu-10.10-desktop-amd64.iso iso
     sudo mount -t squashfs -o loop iso/casper/filesystem.squashfs source
     sudo cp -pLr source/* pathtomountedusbstick
     
     (Thanks Klaas Hartmann for the workaround :))
