Binary package hint: ubiquity

The description of this bug report might also read "Ubiquity causes kernel to *lose* the /dev/sda5 partition". The installer fails because one of the partitions it is trying to prepare *disappears* as a result of one of the many scan/file-system detection operations that ubiquity/partman perform. I've been unable to pin-point the culprit so far. Checking /proc/partitions shows that sda5 has gone missing.

Although I'm testing Jaunty amd64 alpha 3 LiveCD, this bug also occurs using the Intrepid amd64 LiveCD.

The Sony Vaio (laptop) has a single new SATA 400GB. It has been organised thus:

/dev/sda1 Windows Recovery ntfs ~9GB
/dev/sda2 Windows Vista ntfs ~28GB
/dev/sda3 Linux swap ~4GB
/dev/sda4 extended
/dev/sda5 Linux ext3 ~125MB
/dev/sda6 Linux LVM

Once the LiveCD environment starts I install LVM and cryptsetup, 'mount' the LVM volumes and unlock them (each is secured using LUKS and a key-file.

VG = Ubuntu
LVs (in /dev/Ubuntu/) = Jaunty, Jaunty_var, home
encrypted (in /dev/mapper) = root (ext4), var ext4), home (ext3)

sda3 is for swap
sda5 is for /boot/ (ext3)
