Problem while upgrading from ubuntu 8.10 to 9.04

I upgraded my desktop from ubuntu 8.10 to 9.04. During this upgrade I got the following errors during the upgrade.

Setting up gnome-themes-selected (2.26.0-0ubuntu1) ...
gtk-update-icon-cache: No theme index file.dpkg: error processing gnome-themes-selected (--configure):
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
gnome-themes-selected

This occurred during the installation of the package gnome-themes-selected because of the missing of index.theme file in /usr/share/icons/Mist/ in my machine. I fixed it by copying the index file from another machine and running sudo apt-get install gnome-themes-selected

This is my first post. I want to write about how I was able to rectify some of the problems while using ubuntu in my blog. I would be delighted if my solutions work for some others.
