Exploring VirtualBox: Installation and Uninstallation Processes on Linux Mint 21

VirtualBox is a widely used, open-source, and cross-platform virtualization application that enables users to run multiple operating systems simultaneously on their computer. With VirtualBox, users can create virtual machines of different operating systems like Windows, Linux, and macOS on a single physical machine.

This article provides an insight into VirtualBox and its installation process on Linux Mint 21. Let’s dive in!

What is VirtualBox and its benefits:

VirtualBox is a free virtualization software developed by Oracle Corporation.

It allows users to run multiple operating systems on a single device, which can be useful for a variety of purposes like software development, testing applications, or running legacy software that may not be compatible with newer operating systems. One of the significant benefits of VirtualBox is that it’s cross-platform, meaning users can install it on Windows, macOS, and Linux.

This feature makes it a popular choice among developers who work with different operating systems. Another essential benefit of VirtualBox is its flexibility.

It allows users to allocate and adjust the virtual machine’s CPU, RAM, and storage, according to their needs. Users can also create and manage virtual networks, making it easy to simulate networking between multiple virtual machines.

Installation process of VirtualBox on Linux Mint 21:

Before installing VirtualBox on Linux Mint 21, we need to update the system repository and install some dependencies. Updating the system repository:

To update the system repository, open the terminal by pressing Ctrl+Alt+T.

Type the following command and hit Enter:

sudo apt update

This command will download the updated information of all the packages available on the server.

Installing Dependencies:

Next, we need to install some dependencies that are required for the virtualization software to function correctly.

Type the following command in the terminal and hit Enter:

sudo apt install dkms build-essential linux-headers-$(uname -r)

This command installs the dkms package, which is used to manage and install kernel modules that are not included in the distribution’s kernel sources. The build-essential package provides necessary compilers and libraries required for software building, while the linux-headers package provides the kernel headers required for VirtualBox’s kernel modules.

Installation of VirtualBox:

Once the dependencies are installed, we can now proceed to the installation process. Here are the steps:

Step 1: Download the VirtualBox package:

Go to the official VirtualBox download page and select the “Linux distributions” tab.

Choose “Ubuntu 20.04” as the distribution, and download the package according to your device’s architecture. Alternatively, you can use the following command to download the package:

wget https://download.

virtualbox.org/

virtualbox/6.1.26/

virtualbox-6.1_6.1.26-145957~Ubuntu~focal_amd64.deb

Step 2: Install the downloaded package:

Once the package is downloaded, navigate to the location where it is downloaded, and run the following command in the terminal:

sudo dpkg -i

virtualbox-6.1_6.1.26-145957~Ubuntu~focal_amd64.deb

This command installs the downloaded package. However, if you encounter any dependency-related issues, run the following command to install the missing dependencies:

sudo apt –fix-broken install

Step 3: Verify the installation:

After the installation is complete, verify that VirtualBox is installed correctly. Type the following command in the terminal:

virtualbox

This command should open the VirtualBox application. If it doesn’t, try to restart the system and repeat the command.

Updating system repository before installation:

Keeping our Linux Mint 21 system updated is essential before installing any software to avoid any conflicts. To update the repository, enter the following command in the terminal and hit Enter:

sudo apt update

This command downloads the updated package information of all the installed packages on your system. Importing key and repository for VirtualBox installation:

For proper installation of VirtualBox, we need to import the key and repository from its official site.

Here’s how:

Step 1: Download and add the GPG key:

Enter the following command to download and add the key:

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

This command downloads the key from the official site and adds it to the repository.

Step 2: Add the VirtualBox repository:

Enter the following command to add the VirtualBox repository:

sudo add-apt-repository “deb [arch=amd64] https://download. virtualbox.org/

virtualbox/debian $(lsb_release -cs) contrib”

This command adds the VirtualBox repository to the system.

Step 3: Update the system repository:

Type the following command to update the repository:

sudo apt update

This command updates the repository, including VirtualBox’s repository. Step 4: Install VirtualBox:

To install VirtualBox, type the following command:

sudo apt install

virtualbox-6.1

This command installs the latest version of VirtualBox on your system.

Conclusion:

In conclusion, VirtualBox is an excellent virtualization software that allows users to run multiple operating systems simultaneously on a single physical machine. We have shown you how to install VirtualBox on Linux Mint 21 and import necessary key and repository.

We recommend keeping your Linux Mint 21 system updated regularly to avoid any issues with the installation process. Happy virtualizing!

Getting required setup for VirtualBox installation:

Before we proceed with the installation, we need to make sure that our system meets the minimum requirements to run VirtualBox.

Here are the requirements:

– At least 1 GB of RAM (2 GB or more recommended)
