Comment 5 for bug 636478

It is really improbable that a download mistake would allow a regular installation run and then cause such an error. But yes, I've checked on your request, and the MD5 is correct.

Yes, the machine has hardware virtualisation. But actually I am not sure whether VirtualBox makes use of it.

What does "use testdrive instead" mean?

What does that mean "not using a software package provided by the official Ubuntu repositories" ? It is the official 10.10 beta netbook image. Nothing else. Should run under any virtual machine (and the virtual machine can't be the reason for missing files).
