How to completely remove VirtualBox in Ubuntu 16.04?

Question:

I had installed VirtualBox but it started giving me problems. So I uninstalled it using:-

sudo apt-get remove virtualbox-\*

sudo apt-get purge virtualbox-\*

But when I reinstalled VirtualBox it again resumed to previous settings and started giving same problems. How can i completely remove VirtualBox from my laptop and then reinstall it such that it wont give same problem again?

Solution:

Your problem: Virtual Box keeps its folder and settings in your home folder. Delete everything inside the folder.

Uninstall VirtualBox first.

sudo apt-get remove --purge virtualbox 

Run these commands to delete all virtual machines and settings and Virtual Hard Drives:

sudo rm ~/"VirtualBox VMs" -Rf

sudo rm ~/.config/VirtualBox/ -Rf

If you want to install it again. Run this command:

sudo apt-get install virtualbox
