I do click the Add PPA Button first every time, I have even deleted the downloaded file many times in the hope that downloading it again would solve anything. First the system asks for my Admin password, then a progress bar informs that files are being downloaded, it disappears, and then the could not install message appears.
This goes on every time.
Just now I ran a "sudo aptitude update", did the whole process again, and same results.
