The bug occured but the program had been installed succesfully. The problem was that in software center there still was an "Install" button. So I was unable to neitehr get rid of it or install it properly. Software Center didn't work as it should so I tried to open Synaptic. When I did it a message appeared to run in a terminal "sudo dpkg --configure -a". After that I easily got rid of the improperly installed program and was able to give another try which was succesful.
