I have virtualbox, i don't remember how i did download it. I want to update, so i am going to delete this version. To use my virtualbox i type virtualbox in terminal, but when i type sudo apt-get remove virtualbox it says;

Reading package lists... Done

Building dependency tree       

Reading state information... Done

Package 'virtualbox' is not installed, so not removed

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

So how am i supposed to uninstall it?

The package is not called Virtualbox probably. One way to find out the name is to type

aptitude search virtualbox*

in a terminal and it's going to show you all the virtualbox related packages including the one installed. Installed packages begin with letter i.

Another way is to use synaptic and type virtualbox in the search box. It will show you how the installed packages are called.

Depending on your version... try this command

sudo apt-get remove VirtualBox-5.1

Find your version by launching the app, then select Help->About. You will get a long version number (eg. 5.1.18r114002). Ignore anything past the second decimal point; in my case it is version "5.1".

If you didn't install it from the repsoitories and you can't find it with dpkg -l you may have obtained it from the Oracle website and installed it manually. If so, this quote from section 2.3.3.4 (Pg 40) of the manual relates to your situation.

Before updating or uninstalling VirtualBox, you must terminate any virtual machines which are

currently running and exit the VirtualBox or VBoxSVC applications. To update VirtualBox, simply

run the installer of the updated version. To uninstall VirtualBox, invoke the installer like this:

sudo ./VirtualBox.run uninstall

or as root

./VirtualBox.run uninstall

. Starting with version 2.2.2, you can uninstall the .run package by invoking

/opt/VirtualBox/uninstall.sh

To manually uninstall VirtualBox, simply undo the steps in the manual installation in reverse

order. 

If you have manually installed the Virtualbox package from Oracle's website, use this:

sudo dpkg -r virtualbox-5.2

Change the "5.2" for the version that you have installed.

If you need to check the virtualbox version installed in you pc, use this:

dpkg-query --show |grep -i virtualbox

Run the following commands:

$ whereis vbox

copy all the folders in the output

$ sudo rm -rf (all the folders)



$ whereis virtualbox

copy all the folders in the output

$ sudo rm -rf (all folders)



$ sudo apt-get remove virtualbox-* --purge

This is how i removed it. Hope it helps.
