Intrepid to Jaunty upgrade - disk uuid missing

Bug #365669 reported by Félim Whiteley on 2009-04-23
Affects Status Importance Assigned to Milestone

Bug Description

Upgrade from Intrepid to Jaunty (Intrepid was fresh install from Alternate install CD using full disk encryption and LVM). Jaunty upgrade went ok, removed old Kernels and packages, but on reboot there was a long timeout approx 6 secs into dmesg, the timeout taking approx 3mins before busybox came up.

Initial thought was the initramfs not properly built for disk encryption as per bug #317297. This was false assumption, turned out the symlink from /de/disk/by-uuid/disks_uuid_number -> /dev/sda5 was missing, causing crypt modules to not be loaded.

Create symnlink manually, ctrl-d out of busybox and it immediatly asked for passphrase to decrypt drive. System booted, although currentl with no GDM, suspicion of bad upgrade. This is weird as there was no warning/errors in Synaptic/update-manager while still intrepid.

I think this may be an update-initramfs error. I've jsut run an dpkg-reconfigure -a and got the following error at he end:

update-initramfs: Generating /boot/initrd.img-2.6.28-11-generic
cpio: ./sbin/udevadm: Function stat failed: No such file or directory
update-initramfs: failed for /boot/initrd.img-2.6.28-11-generic

On reboot of system it unsurprisingly did not work.

Reinstall the packet "udev" and execute "update-initramfs"

   apt-get --reinstall install udev

Unfortuntly the ramdisk is unable to complete, so that command wouldn't work, that being said I gave up and did a fresh install, the laptop was useless for a week.

Sorry I couldn't leave it around. I will try replicate with another laptop but it might have been a once off event.

Hi Fabio,

It doesn't appear to be, although I've only done fresh installs for the last couple of rebuilds. This was on an older machine which has since been rebuilt with a fresh install of Lucid and the problem did not occur.
