NEW install fails - virtualbox-5.1_5.1.18-114002~Debian~jessie_i386.deb

[m0glj]

Hi All

I have just completed an install of a DEBIAN 8 server. I have then tried to install virtualbox-5.1 and the following is the result.

root@debian:~# root@debian:~# apt-get -f install virtualbox-5.1
bash: root@debian:~#: command not found
root@debian:~# apt-get install virtualbox-5.1
Reading package lists... Done

virtualbox-5.1 is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
virtualbox-5.1 : Depends: libgl1-mesa-glx but it is not going to be installed or
libgl1
Depends: libqt5core5a (>= 5.3.0) but it is not going to be installed
Depends: libqt5gui5 (>= 5.3.0) but it is not going to be installed
Depends: libqt5opengl5 (>= 5.0.2) but it is not going to be installed
Depends: libqt5printsupport5 (>= 5.0.2) but it is not going to be installed
Depends: libqt5widgets5 (>= 5.2.0) but it is not going to be installed
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
Depends: libvpx1 (>= 1.0.0) but it is not going to be installed
Depends: libxmu6 but it is not going to be installed
Depends: libxt6 but it is not going to be installed
Recommends: libasound2
Recommends: libpulse0 but it is not going to be installed
Recommends: libsdl-ttf2.0-0 but it is not going to be installed
Recommends: linux-image but it is not installable
Recommends: pdf-viewer
Recommends: libgl1
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

How do I fix these issues? I am new to Linux and Debian so any help that work would be great.

Thanks

Dependencies can be installed one at a time or just run apt-get -f install and it will pick them up if they are available in your repository.
You probably also need to run apt-get update && apt-get upgrade to get the latest packages for your OS.

...been there,... done that.
now VBox 5.1 is running fine... exept for some gnome glitches, not present before the install
like it is complaining at screensaver intervals, that some application (VBox being the only one active) stopping proper lockdown of the desktop, and more...

One thing really annoying is popping up though, and - strangely - only in the 2 VM's using jessie as a guest:
After every shutdown and restart of the VM, the coordinates (screen position) get picked up correctly, but NOT the SIZE on the screen. For OTHER VM's - including stretch - this is working fine, but with jessie OS, this is getting annoying!
