Gah! I’ve upgraded to 9.10; then on a subsequent reboot I was “slimming down my system” more on that later and have messed up “mountall” causing it to error on boot in standard and recovery mode. Won’t boot, not even to a console.

Mountall error gives status 127

I’m sure I’m guilty of this but I wish people would say “I don’t know” when they have no clue what they’re talking about .

This has absolutely nothing to do with X windows.

The system is failing to mount the drives properly (access the hard drive partitions) – the only fix I’ve seen is to use a rescue disk (your Kubuntu install disk will do). Then:

• chroot from the disk to your broken root partition,
  e.g. “sudo mkdir /media/sda1; sudo mount -t auto /dev/sda1 /media/sda1; chroot /media/sda1” (depends on your setup, use “fdisk -l /dev/sda” if you’re not sure of your root partition, could be on sdb, sdc, sdd too) and
• complete the “sudo apt-get dist-upgrade”.

YMMV, sorry.

chroot gotcha

If you get an “exec format error” when you’re trying to use chroot, as in the above fix, then it’s likely because you’re using a rescue disk from a different architecture (e.g. i386 rescue disk on x86-64 system, or whatever). You’ll need to fix that in teh obvious way.
