[Bug 1168115] Re: Ubiquity does not support LUKS in manual partitioning mode

[nicholas]

I don't know what version of Ubuntu I was installing when I first
attempted manual partitioning with LUKS (manually configured), but I
know I've run into this issue with at least 14.04 and 18.04. At the time
that I first had an issue with it, I poked around until I found out what
the problem was and fixed it manually during installation time. Since
then, I recently put together (a script)[https://github.com/nbros652
/LUKS-guided-manual-partitioning] that enables semi-manual partitioning
with LUKS. The goal of my script is not to cover all use cases, but to
make it possible to do manual paritioning with LVM and LUKS. If you know
how to set up logical volumes, it's not difficult to add more partitions
manually. What my script does is configure the boot, EFI (if necessary),
LUKS and LVM (swap and home) partitions with a few prompts for
information from the user. Then it waits for the user to perform
installation on the configured partitions. Once installation is
completely my script finishes everything off by remounting the system,
generating the /etc/crypttab file, chrooting into the installed system
and updating the initramfs.

Title:
  Ubiquity does not support LUKS in manual partitioning mode

Status in ubiquity package in Ubuntu:
  Triaged

Bug description:
  After installing (daily build) into an existing lvm, no crypttab was
  generated in /etc/

  after installing oneiric versions of cryptsetup it appeared - upgrading to rarings cryptsetup version didn't delete the file and made it usable.
  Installing previous Versions in raring itself didn't bring me the crypttab file, so I guess this is not a daily build problem.
  Couldn't find any info about crypttab being deprecated

  Thank you
