When you install VirtualBox 5.1 on Ubuntu 16.04,you may encounter following error:

Done virtualBox-5.1 is already the newest version (5.1.14-112924~Ubuntu~xenial). You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: libmagickcore-6.q16-2 : Depends: imagemagick-common (= 8:6.8.9.9-7ubuntu5.1) but 8:6.8.9.9-7ubuntu5 is to be installed libmagickwand-6.q16-2 : Depends: imagemagick-common (= 8:6.8.9.9-7ubuntu5.1) but 8:6.8.9.9-7ubuntu5 is to be installed virtualBox-5.1 : Depends: libqt5x11extras5 (>= 5.1.0) but it is not going to be installed Depends: libsdl1.2debian (>= 1.2.11) but it is not going to be installed Recommends: libsdl-ttf2.0-0 but it is not going to be installed E: Unmet dependencies.
