This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


It seems that the ppa you added that is available longer or added outdated PPA. you have to type following command in terminal to install skype.

sudo sh -c "echo 'deb http://archive.canonical.com/ubuntu/ quantal partner' >> /etc/apt/sources.list.d/canonical_partner.list"
