Raspberry Pi Disk Encryption issues

Hi everyone,

I have an issue with my image of ARM Kali (kali-2.1-rpi2). I am following the instructions on https://www.offensive-security.com/k...sk-encryption/ to encrypt my kali image but when I get to this step mkinitramfs -o /boot/initramfs.g 3.18.16-v7 I get the following error

Code:

---

root@kali:~# ls -l /lib/modules/ |awk -F" " '{print $9}'

3.18.16-v7
root@kali:~# mkinitramfs -o /boot/initramfs.g 3.18.16-v7
cryptsetup: WARNING: failed to detect canonical device of /dev/mmcblk0p2
cryptsetup: WARNING: could not determine root device from /etc/fstab
dropbear: WARNING: Invalid authorized_keys file, remote unlocking of cryptroot via ssh won't work!
root@kali:~#

Can someone assist me in figuring out what I am doing wrong? i am following the instructions verbatim as I cannot carry on with the remaining sections in that link.

I had the same problem, you have to change the nick name /dev/blablabla to the real name meaning the uuid in the file /etc/fstab

Code:

---

# <file system> <mount point>  <type>  <options>      <dump>  <pass>
proc /proc proc nodev,noexec,nosuid 0  0
#/dev/mmcblk0p2 / ext4 errors=remount-ro 0 1
UUID=5000bb00-3581-4f00-b858-dd4110f0a0bb / ext4 errors=remount-ro 0 1
# Change this if you add a swap partition or file
#/dev/SWAP none swap sw 0 0
#/dev/mmcblk0p1 /boot vfat noauto 0 0
UUID=2CBE-0EF0 /boot vfat noauto 0 0

blkid will give your the uuid that you need.
I think you sould ignore the error: Unsupported ioctl: cmd=0x5331

make an ssh key rename the public key to authorized_keys and copy it to /etc/dropper-initramfs
