Bug Description

When I tried to install this version the process stucks at "Load installer components from CD".

Doing a CD integrity check this package: "./pool/main/l/linux-signed-lts-quantal/linux-signed-image-3.5.0-23.35~precise1_amd64.deb" (md5 checksum failed) is the failing (maybe there are other, but the tests stops at the first error).

Note: "lts-quantal"

I tried this over USB Sticks (2) making them bootable with Universal USB Installer and LiLi USB Creator.

I tried exactly the same with ubuntu-12.04.1-server-amd64.iso instead of ubuntu-12.04.2-server-amd64.iso and works fine.

I did a MD5 sum check on the downloaded ISO and was OK (af5f788aee1b32c4b2634734309cc9e9).

This appears to be the .deb in the pool with the longest file path, at 104 characters. This also exceeds the purported limit on long Joliet filenames according to the genisoimage manpage (103 characters).

However, this is a limit only on Joliet extensions, it is *not* a limitation on filenames using Rock Ridge extensions; and Ubuntu images are built with both, with Rock Ridge taking precedence at mount time under Linux. So if this file is giving problems, I suspect that the image has been damaged by the tools used to create the USB image.

I have booted the 12.04.2 server image locally under a VM, both as a CD ROM device and as a USB device, and it passes the disc defect check in both modes.

Please use a more reliable method for mastering your USB image:
 - Startup Disk Creator in Ubuntu
 - writing it to a CD instead of to a USB stick
 - writing it to the USB disk with a raw write tool, instead of a tool that (apparently) modifies the image when writing it out.
