I have currently set up a preseeded netboot installation for Ubuntu 8.04 Hardy and it has worked fairly well for a week or two.

Now mysteriously enough the installer fails with the error message "Failed to load installer component - Loading libntfs-3g23-udeb failed for unknown reasons. Aborting." in the download installer components phase.

I have tried this several other mirrors, with and without preseed and it always fails the same way. I even enabled BOOT_DEBUG=2 but the installation log does not give out any additional information on this matter.
