I was trying to install a program using apt-get and it installed incorrectly. It was having some bugs. So I did sudo apt-get purge. Now I want to install it again but when I do apt-get install, it does not download new packages, it uses same old downloaded packages, unpacks it and the program again gets installed incorrectly. How do I remove those old packages.Thanks,
