A little story...
I decided to upgrade an Ubuntu 8.04 install to 9.10.
8.04 to 8.10 went fine.
8.10 to 9.04 broke horribly: the PC seems to have a failing fan which caused
it to overheat and die mid-way through the upgrade. Surprising it booted, sort
of, but when I got to the login page that died, and Alt-F1 got me to a
terminal with a stream of errors stopping me doing a lot.
So I booted from an Ubuntu 9.04 alternative CD, in repair mode, and got myself
a command prompt chrooted to the root partition. I manually mounted the boot
partition, and ran:
apt-get update
dpkg --configure -a
apt-get update
apt-get dist-upgrade
.. then exited, rebooted, and got my system back fully upgraded.
I didn't mention, by the way, that the system boots from a software RAID
array, which "just worked".
I don't expect things to work out like this when something goes horribly
wrong, so it's nice to tell people when they do!
(I used info from here:
http://serverfault.com/questions/8540/recover-from-shutdown-during-ubuntu-distribution-upgrade
.. to get it working.)
I'm now midway through 9.04-9.10, just to prove that I haven't been put off!
