Bug Description

Tested with quantal-desktop-amd64+mac.iso 20120905.2

1. Install a sole quantal (ideally 20120905.2 with lvm and encryption ticked during installation)
2. Carry out another installation using ubiquity ( not via live session route)
3. It could be noted that no side-by-side installation option being present there

(quitting the installer at this point results in 1027648, which i hear is a generic error message)

Given that we do not currently have a way to unlock encrypted volumes and it is unsafe to resize locked encrypted volumes (could result in dataloss), the current behaviour is correct and prevents data loss.

Even if we do unlock encrypted volume - resizing the stack of LUKS + LVM + Filesystems is very tricky ( I did do this manually once and it's a few steps) and I am sure partman does not support this (at least parman-lvm does not).

Also I am not sure what the expectation is on which level to do the side-by-side install:
* crypt | new install
* crypt -> (lvm group | new install)
* crypt -> lvm group -> (logical volume current | logical volume new install)

This is not the complexity I am willing to expose in the automatic partitioning.

Changed in ubiquity (Ubuntu):
