Hi there,
This seems to be the relevant part:
device-mapper: table ioctl on sda6_crypt failed: No such device or address
Command failed
cryptsetup: WARNING: failed to determine cipher modules to load for
sda6_crypt
It basically tells you your cryptodevice is missing and thus no info
could be grabbed which in turn does not include cryptsetup etc. into
your initramfs.
When booting into the live system, unlock and mount your stuff before
chrooting and make sure that all the mapper names are EXACTLY as
expected by mkinitramfs (update-initramfs). ESP: Consult your crypttab
file to find the name. Once the mapped device (as noted in crypttab) can
be found running update-initramfs should work and include everything
that is needed.
Regards
-Sven
P.S.: If I am not mistaken your mapping is supposed to be called
sda6_crypt, while bootrepair gave it a UUID-based name. So you'll
probably have to work this through manually, I guess.

Hello,
I would really appreciate any help to make my system boot properly
again. I can manually mount my encrypted partitions and they unlock
correctly, so I'm pretty sure that I haven't lost my data, but something
that used to work in the Ubuntu 16.04 boot process to unlock and boot
the partitions must have broken, as whenever I boot now, typing my
password no longer unlocks and boots Ubuntu. Instead it says:
“cryptsetup: cryptsetup failed, bad password or options?”
If I press escape and get to the console output, it says:
/scripts/local-top/cryptroot: line 1: /sbin/cryptsetup: not found over
and over.
In case the history is relevant, I recently had to reinstall Windows on
a dual-boot machine. That meant that I had to use boot repair to get my
Grub back. I now have what seems to be a working Grub, but when I boot
into Ubuntu and enter my password into the “Please unlock disk
sda6_crypt”, it fails as described.
http://paste.ubuntu.com/16443425/
was the output of the boot-repair reconfiguration of Grub.
I booted in with a live CD and chrooted into my installation. I did an
apt-get update and apt-get upgrade and I see the following in the output:
Processing triggers for initramfs-tools (0.122ubuntu8) ...
update-initramfs: Generating /boot/initrd.img-4.4.0-22-generic
device-mapper: table ioctl on sda6_crypt failed: No such device or address
Command failed
cryptsetup: WARNING: failed to determine cipher modules to load for
sda6_crypt
I asked for help here:

but nobody has had any ideas so far.
Any ideas would be greatly, greatly appreciated.
Kind regards,
Aaron
