Upgrade issues

Hello world

Yes I know I am freaking lazy for not doing this well in time, but I thought of upgrading to 9.10 from 9.04 just a day ago. However seamless ubuntu people try to make the upgradation process , crap happens. I do not how, but I ran into a major issue with the upgrade. The system was left in an unbootable state after the upgrade, with a failure to mount the filesystems with an mountall error code 127.
Some links which can prove lifesavers as they did for me are:

The only simple reason for the failure to boot is broken dependencies. It is always great to have a live cd to boot into and internet connection through wireless or lan. You'll need to mount your required partitions (root, boot, proc, sys, dev) manually using the live cd and correct th dependency issues as well as do a clean upgrade.

In case the method mentioned in the above links leads to mountall error code 1 as it did for me or you dont have a live cd, then you should have wired internet connection. Using the ESC key drop to the maintenance shell and perform the following steps:
1. Sudo and manually mount root as r/w and override the default read only mount happening otherwise.
mount -o remount,rw /
2. Reconfigure you packages
sudo dpkg --configure -a
3. Perform an upgrade
sudo apt-get update
sudo apt-get upgrade


This should pretty much resolve your problem.
Remember next time to create a custom live cd for yourself you never know when you might fall into a hardware failure.
