virtualbox update? what to choose..

[asa]

hey thanks for the quick response, i installed it from the add additional software and do not see that file in /usr/share/virtualbox/

but i do see it when i go to the remove/install software, along with other options to check/install. should i install it from this or do it manually like sudo apt-get or the website you mentioned? seems to be three different ways to install these? i had it working once with linux lite 1.0 but wanted to find the best way in installing it because i had a lot of issues with crashes so figured to ask which is the best way to install this extra?

thanks again
