This bugs seems related to USB installer, I installed Oneiric successfully using CD via external usb cd-rom.
I will give it more tries to nail down the problem.

Does it always fail? And when it fails, does it always stop at time zone setting?

Hi Jesse,
I tried the USB installer for few times. It shows multiple symptoms.
The case most reproduced is as the image attached.
And the whole installation can't be finished always.

Added the full log from installer.
Please unpack the files with apport-unpack.

According to the screenshot in #4, installer is trying to create a file system on partition #20 of sda, but there are only sda[[1-16] in the /dev, that's why mkfs fails.

Anthony Wong (anthonywong) wrote :

Confirmed with Jesse that this bug is not specific to this hardware. It is a generic issue in the installer which cannot support more than 16 partitions.

Remove all the existing partitions (except two dell partitions), and install oneiric twice without problem so far.
Try to create up to 20 partitions in the fdisk phase of installer, but I can only get sda[1-16] in /dev.
Boot up with an installed oneiric, there are sda[17-22] in /dev.
So this should not be a bug of kernel/driver, and not specific to Vostro V131.

Open a shell and use 'fdisk' to add new partitions, device files would be created in /dev accordingly. But if installer is used for partitions adding, device file will not be created for partition number > 16.
May be an issue of partman.

Let's keep only the ubiquity task open. This is no longer blocking certification.

Tim, can you test it with a daily iimage of Precise, to see if it happens with Precise (when having a lot of partitions).

I created more than 15 partition and installed Precise daily image on the system. This bug can be reproduced.
The partition table before processing installation is as below table.
1)The installation menu
2) failed
3) The installer asks to upgrade the installed Ubuntu.
