Thanks Gary, As given instruction and comment in bug 1014277, you are correct. It was a duplicate.
I am giving another screenshot now. Note that, I have a local repository from which i can install downloaded packages with apt-get. Only not with USC. And i also not doing install by double clicking on deb file. Though the install button is greyed out in that case also.
