Ubuntu – Upgrade virtualbox to 5.0.16

upgradevirtualbox

I have virtual box 5.0.14 on my Ubuntu with extension Pack 5.0.16 which makes virtual box stop working. how do I upgrade my VB to latest version? I followed instruction in the screen shot but there are some errors. when I add Virtual box repository via the second command nothing just happens. then I run the Oracle Public Key downloading command (third one in the picture) it returns this: no valid OpenPGP data found. I run "sudo apt-get install dkms" and it says dkms is already the newest version.
what am I missing here?

Actually I want to upgrade VB rather downgrading the Extension pack. I looked at the official website, it says I have to add a source to my source list but when I add the line in terminal I get this.

I even tried to add it form the software center but it didn't work. obviously there is a way to install the latest version, isn't it? why is this getting so mixed up?!!

There are 2 methods to get around this issue:

  1. Upgrade VirtualBox
  2. Remove the problematic Extension Pack

1. Upgrade VirtualBox

Several ways to do this but for a pure commandline method try the following; first adding repository details for Wily Werewolf (copying and pasting one line at a time):

echo "deb http://download.virtualbox.org/virtualbox/debian wily contrib" | sudo tee -a /etc/apt/sources.list
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -
sudo apt-get update

Then install some support files and then VirtualBox itself:

sudo apt-get install dkms
sudo apt-get install virtualbox-5.0

And on my Wily installation this gets the latest version:

2. Remove the problematic Extension Pack

Rather than install a greater version of VirtualBox, as demonstrated in poin t) you could simply remove the offending extension pack. On my own system: first list the Extension Packs installed:

andrew@ilium~$ vboxmanage list extpacks
Extension Packs: 1
Pack no. 0:   Oracle VM VirtualBox Extension Pack
Version:      5.0.8
Revision:     103449
Edition:      
Description:  USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption.
VRDE Module:  VBoxVRDP
Usable:       true 
Why unusable: 
andrew@ilium~$

The uninstall the Extension Pack:

andrew@ilium~$ sudo VBoxManage extpack uninstall "Oracle VM VirtualBox Extension Pack"
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
Successfully uninstalled "Oracle VM VirtualBox Extension Pack".
andrew@ilium~$

Now VirtualBox should start...
