Bug Description

Binary package hint: ubiquity

1. Start ubquity
2. Go to step 6 of 7 ('Prepare disk space')
3. Choose 'manually edit partition table' and click 'forward'

Expected result:
Physical disks, and lvm vg's are treated as being conceptually
the same. Ditto partitions and lvm lv's.

Actual result:
lvm lv's are treated as being physical disks.

The lvm lv's appear in the drop-down list of disks. Selecting one
shows a fake partition in the partition list, the name of which is the
path of the lv with a 1 appended. There is a warning sign beside the

On the page where you choose what partition is mounted where, the lvm lv's are completely absent from the drop-down lists.

This has been tested on dapper live beta1, dapper live beta2, and
on an installed dapper system uptodate as of today (2006/05/07).

What distribution (Ubuntu, Kubuntu, etc.) are you installing?

I've arranged for LVM partitions not to appear in the autopartitioner's disk selector, which was just a bug (specifically, bug 32845). You seem to be suggesting that there's a bug in the manual partitioner as well, though, so I need to know whether this is the GTK or the KDE frontend.

The bug here is really that LVM partitions are offered at all. LVM partitions are intentionally not supported by the live installer; we decided that we don't have time to do a reasonable job on this for Dapper, so it's better to disable support for them. The text-mode install CD still supports them.

Ubuntu with the gtk frontend in all three cases. I'm happy to try other frontends too if that's useful.

Re: bug 32845, ah, yes, i had seen that behaviour previously, and had been wondering when it had been fixed. cool.

Re: no lvm for live installer, sure, that makes perfect sense. I've used the text-mode install on the 2 affected machines with no problems.

Ubuntu Desktop CD 20060523.2: when I got to step 6, it offered me two options:
- Erase entire disk: LVM VG vg, LV vmware - 10.7 GB Unknown
- Manually edit partition table

I think the first option is plain wrong, as it offer one of my LVM volumes (named vmware) as physical disk to be erased. It should show /dev/hda instead - which is actual disk with 3 partitions: Linux (primary), LVM (primary) and extended (unallocated space).

When I have deactivated LVM volume group (sudo vgchange -a n vg), ubiquity has offered appropriate options:
- Erase entire disk: IDE1 master (hda) 60 GB
- Use the largest continous free space
- Manually edit partition table

Confirmed in Ubuntu Dapper Release Candidate, this bug shows up in Desktop Live CD too (gtk installer).

Same bug still in 14.04 LTS.. I installed ubuntu 13.10 on a brand new laptop, and, silly me, I checked the LVM option.

Now, when trying to install 14.04 on top of 13.10 (I did an online "live upgrade" from 13.10 to 14.04 but it broke my installation), the only option I have, is to wipe out the entire disk.

.. that is because the 14.04 installer does not recognize LVM .. it says that my laptop "has no detected OS"..!

Maybe the best option would be to remove the LVM possibility completely from the installer .. or give adequate warnings, like "choosing this option makes upgrading to a new ubuntu version impossible".
