Here are instructions to reproduce the issue in a KVM/QEMU virtual machine using a live-CD ISO image. They create a qcow2 image, mount it using nbd, create the 'faulty' partition table using 'fdisk -u', and then start the VM guest with the live-CD.
qemu-img create -f qcow2 ubuntu-jaunty-install-test.qcow2 3500M sudo modprobe nbd sudo qemu-nbd -c /dev/nbd0 ubuntu-jaunty-install-test.qcow2 echo -e "o\nn\np\n1\n\n+100M\nt\n27\nn\np\n2\n\n+250M\nt\n2\n7\nn\np\n3\n\n+250M\nn\ne\n\n\nn\n\n+400M\nn\n\n\np\nw\n" | sudo fdisk -u /dev/nbd0 sudo nbd-client -d /dev/nbd0 sudo losetup /dev/loop2 jaunty-desktop-amd64-alpha4.iso kvm -m 512 -boot d -cdrom /dev/loop2 -hda ubuntu-jaunty-install- test.qcow2 # when finished, do: sudo losetup -d /dev/loop2 Start the desktop installer. When the Partitioning page is reached, select "Manual" Assign sda3 to /boot Assign sda5 to swap Assign sda6 to / Move on to the installation phase. The partitioner will start-up and then close, returning to the "Prepare disk space" page. In a terminal "cat /proc/partitions" will show that the logical partitions in the sda4 extended container have gone missing. -- Kernel *loses* partitions at partitioning stage; installer fails https://bugs.launchpad.net/bugs/324987 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
