Hi, I tried installing Virtualbox yesterday via the software centre but my wireless connection died part-way through installation. Fixed the wireless issues since then but I still can't get Virtualbox working, I've tried various things to try and get it back but nothing seems to work. Tried

sudo apt-get remove virtualbox
sudo apt-get install virtualbox

and then install dkms. Installed generic headers as per lots of recommendations but no joy.

Tried uninstalling from terminal and then running the installer from Oracle's website but it says "breaks existing package that conflicts: 'virtualbox'"

If anyone can give me any advice it would be very welcome. Thanks
