Latest testing cdimage

[Lucio Crusca <lucio@sulweb.org>]

Hello,

I'm trying to install the latest cd image downloaded from

http://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/debian-testing-amd64-DVD-1.iso

The hardware is a HP 15-G210 NL:

I've disabled Secure Boot and I'm installing from DVD media. When the 
base system install starts I immediately get an error in the installer:

/usr/sbin/debootstrap: line 617: Permission denied.

The installer stops. I suspect it's not a hardware related problem, 
because disk partitioning worked, and I think it could be a bug. How can 
I make it go ahead?
