I am trying to remove whole drive encryption from my Ubuntu installation. I've run Ubuntu from Live CD, mounted crypt partition and copied it to another partition /dev/sda3.

sudo cryptsetup luksOpen /dev/sda5 crypt1
sudo dd if=/dev/ubuntu-vg/root of=/dev/sda3 bs=1M

After that I've run boot-repair: https://help.ubuntu.com/community/Boot-Repair

Added entry to /etc/fstab:

UUID=<uuid> /  ext4 errors=remount-ro 0 1

Of course I've replaced with blkid result of my /dev/sda3. I've also deleted overlayfs and tmpfs lines from /etc/fstab. (I've just compared it to content of /etc/fstab in non-encrypted Ubuntu installation and could not find overlayfs and tmpfs).

I've chrooted from LiveCD into my system and rebuilt initramfs: http://blog.leenix.co.uk/2012/07/evmsactivate-is-not-available-on-boot.html

I've also removed cryptsetup using apt-get remove.

Basically I can easily mount my system partition from Live CD (without setting up the encryption and LVM stuff), but can not boot from it. Instead I see:

cryptsetup: evms_activate is not available

When I've chosen the Recovery mode I've seen this:

Begin: Mounting root file system ...
Begin: Running /script/local-top ...
Reading all physical volumes.
This may take a while ...
No volume groups found
cryptsetup: evms_activate is not available
Begin: Waiting for encrytpted source device ...

My /etc/crypttab is empty.

I am pretty sure that system tries to find encrypted partition, search for LVMs etc.

Do you have ideas what could be the problem or how can I fix it?

Thanks
