2) Through Ubuntu Software Center

3) Downloading the .deb.

Any idea on how do I rectify this and go ahead with the installation?

Open your terminal and write the following commands

1. sudo apt-get update - to update the repositories and package
2. sudo apt-get install gparted - install gparted
3. sudo dpkg -l gparted - check and confirm installation
4. sudo gparted - to open gparted

and you are done :-)

1. Download Gparted as an ISO file
2. Burn it in a USB flash
3. Plug the USB flash into your Computer
4. Start your computer with the bootable USB that you already made
5. Use the Gparted app like live

And good luck
