Ubuntu instalation problems

[Víctor de la Concepción]

Hi all,

I have an error with the base-system every time I try to install Ubuntu 
  in my Ahtec Signal X-9660M laptop: problems searching some basic 
packages (initrd-tools last time).

I have tried with distincts warty daily isos but I have the same results.

Any idea?

Thanks,

Víctor
