I can't log in into ssh to crypt luks encrypted device with installed dropbear but I can while rpi is decrypted. I'm getting error: ssh: connect to host raspberry port 22: No route to host. While booting pi I'm getting error: ipconfig: eth0: SIOCGIFINDEX: No such device at boot. This device is Raspberry Pi with installed Raspbian 9 Stretch operating system. I'm following this guide https://stinkyparkia.wordpress.com/2014/10/14/remote-unlocking-luks-encrypted-lvm-using-dropbear-ssh-in-ubuntu-server-14-04-1-with-static-ipst/. I want configure remotely unlock crypt luks encrypted rpi device. I've set NO_START to 0 and copied ssh keys. The results from ifconfig -a command:
$ sudo ifconfig -a

Notice that 192.168.1.5 is my static ip address that I set in /etc/network/interfaces.
I added the static IP under the DEVICE= line in /etc/initramfs-tools/initramfs.conf:
IP=192.168.1.5::192.168.1.254:255.255.255.0::enxb827eb1b2a72:off
And bottom of file /usr/share/initramfs-tools/scripts/init-bottom/dropbear:
ifconfig enxb827eb1b2a72 0.0.0.0 down
But it nothing work.
The result of command sudo ip route show:
$ sudo ip route show
