Hi, The netboot image found in http://ftp.debian.org/debian/dists/Debian9.4/main/installer-amd64/current/images/netboot/ for Debian 9 seems broken, we use that for unattended installation.
The error msg returned says: "No kernel modules were found. This probably is due to a mismatch between the kernel used by this version of the installer and the kernel version in the archive. If you're installing from a mirror, you can work around this problem by choosing to install a different version of Ubuntu. The install will probably fail to work if you continue without kernel modules" Can someone update the netboot image if it's a bug or any workaround helps to fix this situation would be greatly appreciated. Thanks. Mizuki
