[Bug 1510731] Re: Can't use crypto in manual disk setup Kubuntu 15.10

[Gizmo Chicken]

Have you tried with Ubuntu rather than Kubuntu?  If not, you might want
to try with Ubuntu, just to rule out whether this is a Kubuntu specific
issue.

Using the “something else” option presented during installation of
Ubuntu 15.10 and Ubuntu 16.04 (onto a non-UEFI system with a gpt
formatted drive), I have been able to create a LUKS-encrypted volume on
sda2, and I have been able to install boot (/boot) into non-encrypted
sda1, and root (/) into LUKS-encrypted sda2.

I have noticed, however,  that, after creating the LUKS-encrypted volume
on sda2 (using the create the next partition as "physical volume for
encryption" that you mention), I sometimes have to wait a bit (sometimes
a minute or more) before "sda2_crypt" (or something like that, I don't
recall the exact label) is created, into which I can install root.
Maybe your installation hangs t this point?

Although the above works for me, I have NOT been able to install boot
(/boot) into non-encrypted sda1, root (/) into LUKS-encrypted sda2, and
home (/home) into into LUKS-encrypted sda3. Rather, although I am able
to create all of the LUKS-encrypted volumes, the installer hangs during
installation when the following is displayed:

“Creating ext4 system for /home in partition #1 of Encrypted volume
(sda3_crypt)...”
