Ubuntu-Unity Issues-Font Issues-Dash Home not Finding Applications

Recently I went through this error during Ubuntu update to version 12

A text of white on white was appearin also Dash Home was not finding applications.The result was due to corrupted Unity User Interface.

To correct the same I ran following 2 commands from Terminal

rm ~/.cache/software-center -R

which sorted out my issue of ubuntu sodtware center not running

and then

unity --reset &

which told me to do a complete reinstall of unity via following command

sudo apt-get install unity
