Bug Description

Binary package hint: ubiquity

I tried installing from the Jaunty alpha 5 desktop amd64 CD, and ubiquity couldn't see any partitions. (This was with the 'try Ubuntu' option; subsequently I installed via the 'install Ubuntu' boot option and it found the partitions and installed successfully.)

The only thing I did differently from normal was that I had an SD card in the mmcblk reader. Ubiquity wanted to install to this device in preference to /dev/sda, but reported that there were no operating systems anywhere on the computer. I tried going back in the installer and removing the card so as to re-run the partitioner, but this time it found nothing at all (see attached screenshot).

Pressing 'forward' didn't work as it told me I had to set up a root partition, but since it had found no partitions I couldn't set one up.

I tried again without the SD card inserted and got exactly the same result - ubiquity doesn't report any partitions when you boot in desktop mode from the live CD.

Are these partitions mounted? If you're not sure, please paste the output of `mount` and `sudo parted_devices` from a terminal window.

If they are mounted, can you please unmount them and try again.

Do let us know what the result is either way.

This is often because libparted fails to understand your partition table. Could you please run the following command from the live CD and give us the output:

  sudo od -Ax -tx1 -N512 /dev/sda

How could this be a libparted problem? The live CD recognises the partitions fine if I select 'Install Ubuntu' instead of 'Try Ubuntu' from the boot menu (I've installed four times now this way). In any case I've attached the output as requested. Incidentally, this time when I booted off the live CD (actually a USB key), I just got a command prompt this time and not the desktop.

Also, regarding whether the partitions were mounted or not, the first time I tried some were mounted, but the second time none were.
