Hi Thomas, I found the problem to be the nameserver configured is referring to the faiserver. /etc/resolve.conf I am using a public nameserver 8.8.8.8.
>From the configuration I see that 8.8.8.8 is already set. Where can I change this?

"Temorary failure resolving 'deb.debian.org'" That's why a lot of packages (maybe all) are not installed. Please fix problem, otherwise you will never have a bootable installation. For e.g. grub-efi is not installed, and without grub your computer cannot boot. -- regards Thomas
