Thank you for this very usefull information!
I found this 40CDROM file, but it is blocked (read only) which makes that I cannot remove.
Anyone that can help on how to deblock this read only protection?...

Install from USB fails: "An attempt to configure apt to install
additional packages from the CD failed"
Status in Estobuntu — oma eesti opsüsteem:
Status in “ubiquity” package in Ubuntu:
Status in Baltix GNU/Linux:
Please note that removing /usr/lib/ubiquity/apt-
setup/generators/40cdrom from your system may cause the installer to
crash at a later stage.
Original report follows:
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.
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 :))
