You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
linux-headers-amd64 : Depends: linux-headers-4.9.0-14-amd64 but it is not installable
virtualbox-6.1 : Depends: libc6 (>= 2.28) but 2.27-6 is installed
Depends: libqt5x11extras5 (>= 5.6.0) but it is not installed
Depends: libsdl1.2debian (>= 1.2.11) but it is not installed
Depends: libssl1.1 (>= 1.1.1) but 1.1.0l-1~deb9u2 is installed
Recommends: libsdl-ttf2.0-0 but it is not installed
Recommends: linux-image but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

or run
sudo apt --fix-broken install
also might want to remove the virtualbox repository since Kali is based on Debian Testing not just Debian
sudo gedit /etc/apt/sources.list
