=>>Problem :::Software index is broken
            Cannot add or remove packages

It is impossible to install or remove any software. Please use the package manager
"Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first.



>>>Solution:


Never mind. I figured out how to fix it myself. For anyone else who gets this problem, here is what you need to do:

 >>>  Type in a command window:

           sudo dpkg --configure -a

            It will error out, but don't worry. Find the files causing the problems and

>>>> Type

        sudo dpkg -r PACKAGE_NAME_FOR_WHICH_ERROR_OCCUR 

for each one to remove it. Some of them will fail to be removed. Add them to a list.

>>>> Run

        sudo dpkg --configure PACKAGE_NAME 

for each package in your list. It will configure them. This time, you should not see any errors.
>>>> Run

       sudo apt-get install -f

 Your dependency problems have solved now.

##JOB DONE NO PROBLEM NOW to INSTALL packages.
