Saucy ubiquity crashes with kernel error

[Erick Brunzell]

This is actually just a follow up on bug #1220165 so it should probably be marked as a duplicate, but this time I launched ubiquity from the terminal with the command "ubiquity -d" in hopes that it might provide more helpful info.

I'm testing on bare metal:

Intel Atom CPU 230 @ 1.60GHz
Intel 82945G/GZ Integrated Graphics Controller (rev 02)
Intel N10/ICH 7 Family High Definition Audio Controller (rev 01)
Realtek RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
2GB DDR2 RAM

The existing drive structure is a quite simple dual-boot of Lubuntu Saucy i386 and Ubuntu GNOME Saucy i386 on a physical 80 GB drive:

ubuntu-gnome@ubuntu-gnome:~$ sudo parted -l
Model: ATA WDC WD800BB-63JK (scsi)
Disk /dev/sda: 80.0GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
 1 1049kB 39.7GB 39.7GB primary ext4 boot
 2 39.7GB 80.0GB 40.3GB extended
 6 39.7GB 77.5GB 37.8GB logical ext4
 5 77.5GB 80.0GB 2525MB logical linux-swap(v1)

Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0
has been opened read-only.
Error: Can't have a partition outside the disk!

I also decided this time to record the UUID's prior to trying the install.

ubuntu-gnome@ubuntu-gnome:~$ sudo blkid -c /dev/null
/dev/loop0: TYPE="squashfs"
/dev/sr0: LABEL="Ubuntu-GNOME 13.10 i386" TYPE="iso9660"

/dev/sda6: UUID="13cf3a15-45c3-4eef-bae7-6fa29a4a50b9" TYPE="ext4"

When offered installation options I chose "Erase disk and install Ubuntu GNOME" and shortly thereafter I was presented with that message about the kernel not being informed of modifications, and this is what the new drive/partition info is while ubiquity is still in a frozen state:

ubuntu-gnome@ubuntu-gnome:~$ sudo parted -l

/dev/sda6: UUID="13cf3a15-45c3-4eef-bae7-6fa29a4a50b9" TYPE="ext4"

It's hard for me to read that until I get on another computer that's tweaked for my limited vision so please give me time to review this.

Sorry to be so dense, I hope I didn't make too many typos, and apologies if I'm only wasting electronic ink.

I was even able to boot that pre-existing Ubuntu GNOME install on sda1 after recovering grub, so just to recap:

I had a simple dual boot of Ubuntu GNOME and Lubuntu on a physical 80GB drive.

I then used an Ubuntu GNOME 20131013 i386 image and chose "Erase disk and install Ubuntu GNOME".

What actually happened was that only sda6 was erased. The installer attempted to reuse other partitions but puked!!!

Thanks for the information. Marking as a dup to collect everything together.
