Cannot install nonfree drivers due to dependency problem

I cannot install non-free drivers for my video card due to a problem with dependencies. I try installing drivers via software & updates -> Additional drivers.

For fglrx
$software-properties-gtk
Warning: install transaction not completed successfully: Transaction failed: Pakketafhankelijkheden kunnen niet opgelost worden
 The following packages have unmet dependencies:

fglrx: Depends: libqtcore4 (>= 4:4.8.4) but 4:4.8.6+git49-gbc62005+dfsg-1ubuntu1 is to be installed
       Depends: xorg-video-abi-18 but it is a virtual package

For fglrx-updates
$ software-properties-gtk
Warning: install transaction not completed successfully: Transaction failed: Pakketafhankelijkheden kunnen niet opgelost worden
