package grub-pc 1.98-1ubuntu6 failed to install/upgrade: Crypt/LVM + USB bootstick to blame?

[Tim McCormack]

Binary package hint: grub2

I have a 64-bit laptop that I was trying to upgrade from Ubuntu 9.10 to 10.04. During dist-upgrade, and subsequent attempts to complete a reinstallation of grub-pc, I encountered the attached error. /boot was mounted (see partitioning below) before each attempt, but was found to be unmounted afterwards.

Partitioning setup:

mbr: winboot
sda1: Windows 7
sda2: LUKS "sda2_crypt"
   LVM (1 logical group, named "singleton")
      / (on logical volume "ozzie")
      /home (on logical volume "sweethome")
      swap (on logical volume "bigswap")

There is also a USB stick with the following partitioning:
mbr: GRUB2 stage 1
sdb1: /boot GRUB2 stage 2

The USB stick will prompt me to unlock the main hard drive's LUKS partition, then boot to the Ubuntu OS inside.

Before rebooting after the dist-upgrade, I ran `sudo grub-install --modules="crypto lvm" /dev/sdb`. Everything seemed to work fine.
