I am getting the following error message from the Ubuntu software centre when trying to install Skype for Linux on my Ubuntu 13.04 64 but system:

can anybody help?
Dear all - many thanks for your rapid responses. The answer provided by Qasim did the trick. Probably the other solutions were good too, but I may not have pressed the right buttons when trying them; Copy-pasting Qasim's commands into the terminal worked like a miracle - I had stuff scrolling down the screen for about 5 minutes but then Skype installed and I have already had my first conversation. Long live the AskUbuntu community. Cheers
