I have uninstalled my VirtualBox using
sudo apt-get remove --purge virtualbox-5.2 and the operation was successfull. But when run the command
apt-cache pkgnames virtualbox it shows following result.
So i run
sudo apt-get remove virtualbox but it shows
Package 'virtualbox' is not installed, so not removed. How can iremove those packages?
How to find the names for those packages to uninstall?
