To reproduce:
- Download ubuntu-12.04-alternate-amd64.iso, sha256sum: f8d54df0afbab6a6248f6e2bcab3e68f01c04d52b0bb1f889d880ad3bc881ccb
- Burn it to a USB flash drive from a completely up-to-date Ubuntu 10.04 LTS with UNetbootin
- Install on a machine with no network connectivity

Current behaviour:
- xserver-xorg-video-all fails to install with an error message saying it was because two of its dependencies were not found: xserver-xorg-video-ati and xserver-xorg-video-nouveau

Expected behaviour:
- The install completes successfully

Thoughts:
I suspect this is because, whilst present on the iso, their filenames have been truncated:

./pool/main/x/xserver-xorg-video-ati/xserver-xorg-video-ati_6.14.99~git20111219.aacbd629-0ubuntu2_.deb

and

./pool/main/x/xserver-xorg-video-nouveau/xserver-xorg-video-nouveau_0.0.16+git20111201+b5534a1-1build2.deb

i.e. the filename does not end "_amd64.deb"
