Ok, so this can be caused by numerous reasons, often times not
update-manager's fault as such, but the state of the system before the
upgrade started. For example sometimes people remove critical packages
from Ubuntu and then when they try to upgrade it all falls apart
because some crucial component is missing - like the "ubuntu-desktop"

One interestingly useful command which 'fixes' many issues relating to
bits missing is this:-

sudo apt-get update
sudo apt-get install ubuntu-desktop^

(note the caret on the end). This causes apt to attempt to install the
ubuntu-desktop task which pulls in everything needed for the current
release. It's surprising how many times this actually pulls in
critical components that the user has inadvertently removed in the past.

Unity and compiz crashes can often be attributed to users messing with
compizconfig-settings-manager or sometimes just bugs. I find dropping
to a shell (CTRL+ALT+F1) and issuing this command often helps reset
things back to normal:-

unity --reset &

It's a matter of opinion really. Everyone has their favourite support
site, be that mailing lists, irc, askubuntu, answers, forums.. Each to
their own. Personally Askubuntu beats all of them for numerous reasons.
