Hello. Well, I acted on target with:
apt-cdrom add and I failed. But if I put: apt-cdrom add /media/cdrom works right all the installation process. I changed this line in library.sh and installation has occurred without problems: if ! log-output -t base-installer \ chroot /target apt-cdrom add </dev/null; then error "error while running apt-cdrom" fi else if ! log-output -t base-installer \ chroot /target apt-cdrom add /media/cdrom </dev/null; then error "error while running apt-cdrom" fi else I solved the problem with apt-cdrom indicating the path of the medium.
