To see the full list of changes, go to the wiki page.
How to Install Virtualbox 5.0 in Ubuntu:
1. Before installing the new release, you may first remove the previous release on your system via Synaptic Package Manager, Software Center, or by running below command in terminal (Ctrl+Alt+T):
sudo apt-get remove virtualbox virtualbox-4.* virtualbox-5.0
2. Download Virtualbox 5.0 from the official links below:
select i386 for 32-bit, or amd64 for 64bit system. Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04, and Ubuntu 12.04 are supported so far.
3. After downloaded the package, click to open with Software Center/Gdebi and finally install the Virtualbox 5.0
Addition, to receive future updates and fixes for VBox 5 through Software Updater or your Package Manager, you may add the official Virtualbox repository for Linux
sudo sh -c 'echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -cs) contrib" >> /etc/apt/sources.list.d/virtualbox.list'
The command creates a separate source file for VBox and writes the repository address into it. $(lsb_release -cs) automatically detects your release name, Linux Mint and Elementary OS users have to replace it (e.g., trusty for Mint 17.x and Freya, precise for Mint 13 and Luna).
Also download and insert the keyring so that Ubuntu trusts the package from that repository:
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -
Finally you can upgrade VirtualBox as a part of system updates through Software Updater/Package Manager when a new release is out.
