How to Install Virtualbox 5.2.20 in Ubuntu:

1. Remove old Virtualbox if any, by opening terminal (Ctrl+Alt+T) and running command:

sudo apt-get remove --autoremove virtualbox virtualbox-5.1

2. Download & install the latest Virtualbox package from the link below:

Download VirtualBox for Linux

Finally install the downloaded package via Gdebi (install it via Ubuntu Software) package manager.

3. If you’ve added the Oracle VBox repository, you can directly install the 5.2 release from Synaptic Package Manager or via apt command.

To add the repository, do:

Open terminal (Ctrl+Alt+T) and run command to add the repository:

sudo sh -c 'echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" >> /etc/apt/sources.list.d/virtualbox.list'

for Linux Mint 19, replace $(lsb_release -sc) with bionic in the code.

Setup the keyring so to trust the updates from the repository:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -

wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Finally install virtualbox 5.2 via commands:

sudo apt-get update

sudo apt-get install virtualbox-5.2

With the repository added, you can simply install the future 5.2 series updates via Software Updater.
