Debian Linux: Install Virtualbox Virtualization Software

To install Oracle Virtualbox on Debian Linux, you can follow these steps:

1. Add the Virtualbox repository to your system. Open a terminal and add the following line to the /etc/apt/sources.list file:

deb http://download.virtualbox.org/virtualbox/debian buster contrib

Replace buster with the name of your Debian version (e.g., stretch, jessie, etc.).

2. Download and add the Oracle public key to your system:

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 -

3. Update the package list and install Virtualbox:

sudo apt-get update
sudo apt-get install virtualbox-6.1

This will install Oracle Virtualbox and its dependencies.

4. To start Virtualbox, open the Applications menu and select the Oracle VM Virtualbox entry.

Alternatively, you can start Virtualbox from the terminal by running the virtualbox command.

Keep in mind that Virtualbox requires hardware virtualization support to run virtual machines. Make sure that your system has a CPU with hardware virtualization support and that the virtualization support is enabled in the BIOS or UEFI settings.

If you are having trouble installing Virtualbox or running virtual machines, you can check the Virtualbox documentation or seek assistance from an experienced system administrator.
