I'm likely hitting the same bug. The environment is a Debian Stable virtual machine inside Proxmox.
Update with apt failed, so I tried to manually update initramfs. Also gets stuck on that line: /usr/share/initramfs-tools/scripts/local-top/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/local-premount/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/local-bottom/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/local-block/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/init-top/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/init-premount/ORDER ignored: not executable /usr/share/initramfs-tools/scripts/init-bottom/ORDER ignored: not executable Building cpio /boot/initrd.img-4.9.0-3-amd64.new initramfs ... So I kill the process. # uname -a Linux mplserv 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2 (2017-06-12) x86_64 GNU/Linux I can give more infos if needed, Bisou++
