unable to install quantal on system running precise with LVMs

[James Hunt]

Attempting to install quantal on a system running precise (installed from alternate CD) with LVMs results in ubiquity looping and never allowing the install to proceed:

- On "Installation type" screen, select "erase Ubuntu 12.04 LTS and reinstall"
- click "Install Now"
- On "Erase Ubuntu 12.04 LTS and reinstall" screen, click "Install Now"
- bottom of screen shows "Installing..."
- window appears titled "Remove existing logical volume data?" and tells me I have 2 LVs to remove(root, swap_1) in 1 VG in 1 PV (/dev/sda5).
- click "Continue".
- window disappears and takes me back to "Erase Ubuntu 12.04 LTS and reinstall" screen.
- click "Install Now"
- a moment later the window reverts to the "Installation type" screen.
- clicking "Install Now" just loops round again.

Selecting "Something else" also gives unexpected behaviour since although it shows the VGs, nothing appears to be deletable via this screen, and each VG is shown twice with the 2nd entry indented, like this:

/dev/mapper/myhost-root
    /dev/mapper/myhost-root
/dev/mapper/myhost-swap_1
    /dev/mapper/myhost-swap_1
/dev/sda
    /dev/sda1
    /dev/sda5

The "used" column shows "unknown" for all indented entities.

this is a by-product of introducing lvm and crypto support.
There are a few fixes in the following two branches:
- lp:~dmitrij.ledkov/ubiquity/crypto-done
- lp:~dmitrij.ledkov/partman-crypto/finish.d

Which should be merged soon. Sorry for the temporary / work-in-progress inconvenience.
If you need to re-install *right* now, please use netinst or alternative cds.

[Dimitri John Ledkov (xnox)]

The two branches previously mentioned, are now merged and uploaded. Please way for the next daily (probably 20120809) and try again, once it's available.

[Dimitri John Ledkov (xnox)]

This should not be a problem any more. Please provide further details if it's still a problem for you & set the status back to New.
