(Get the code!)
Even though I don't use Kubuntu, just for kicks, I tried installing Kubuntu 15.10 with boot (/boot) into non-encrypted sda1 and root (/) into LUKS-encrypted sda2. I got the same result as reported by David Schoen, namely, the installer failed to create "sda2_crypt" into which root (/) could be installed.
As I previously noted, I can accomplish this (install boot into non-encrypted sda1 and root into LUKS-encrypted sda2) using Ubuntu 15.10 and Ubuntu 16.04. So this seems to be a Kubuntu specific problem.
For those interested in attempting to accomplish this with Ubuntu 15.10 or Ubuntu 16.04, here are a few tips:
(1) Use a standalone copy of gparted to create at least two partitions, the first (sda1) for boot and the second (sda2) for root. That is, create the desired partitions before starting the Ubuntu installation. Although you could use less, I typically use 1 GB for sda1.
(2) During the Ubuntu install, select the "something else" option. Configure the installer to install boot (/boot) into the non-encrypted sda1. (I typically format sda1 to EXT4, but many recommend using EXT2.) Using the "create physical volume for encryption" option, create a LUKS-encrypted volume on sda2. Wait a bit (sometimes a minute or more), and "sda2_crypt" will appear among the list of installable locations. Configure the installer to install root (/) into the "sda2_crypt" previously created. (I typically format sda2_crypt to EXT4.)
(3) At least as of now, do NOT attempt to install home or any other directories into separate partitions. Just stick to installing boot into sda1 and root into sda2_crypt. (You can have other partitions on your disk, but don't attempt to install anything into them.)
(4) Do NOT attempt to create a swap partition during installation. Instead, acknowledge the warning regarding the lack of swap space during installation and move on to the next step. (You can create a swap file on sda2_crypt once installation is complete. Or if you really want a swap partition, there are ways of creating them after installation, provide you have left some space on your disk when creating partitions using gparted.)
For those who want to install boot (/boot) into non-encrypted sda1, root (/) into LUKS-encrypted sda2, and home (/home) into into LUKS-encrypted sda3, please see my bug report at https:/
