I had the following repository for virtualbox in my /etc/apt/sources.list:
deb ttp://download.virtualbox.org/virtualbox/debian maverick non-free
Then I found out there was a new version when I opened it today (the program prompted me with a window to manually download it from Oracle's site). Then I tried
sudo apt-get update && sudo apt-get upgrade and got nothing.
Here you have a way to add virtualbox-4.0 to your apt-get, but the problem is that it isn't updating, meaning I would have the two installed. I'm also worried if I'll have to do something like that each time it updates since that would defeat the point of apt-get.
I've been using virtualbox with the apt-get update for more than a year now and this is the first time it has happened, so I was wondering if there would be a way to just update my current installation.
