Your current situation is anything but stable. Apparently, there's a bunch of other packages waiting to be installed or waiting for their dependencies to be installed. I was also of the impression that you have roger from the jessie repository installed which is not the case. Here's what I suggest you do. 1) remove the three packages for roger 2) make sure "aptitude install -f" runs through fine 3) "aptitude install roger" (from the jessie repo) 4) try once more what I suggested in yesterday's mail
