Install VirtualBox Guest Additions in Ubuntu

These instructions assume that you have installed a guest Ubuntu system in VirtualBox.

• Open VirtualBox in the host system and start Ubuntu virtual machine.
• Open a terminal and install the following:
• sudo apt install build-essential dkms linux-headers-$(uname -r)
• After the above command is complete, restart the guest Ubuntu system.
• After boot up is complete, go to the VirtualBox menu and select Devices > Insert Guest Additions CD Image. Here’s an example image for your reference (Figure 1).
• Once you do that, you should see a new disk mounted under /run/media/[user name]/ directory. Go to that directory from the terminal.
• Then, execute the setup program VBoxLinuxAdditions.run using the below command.
• sudo ./VBoxLinuxAdditions.run
• Wait for the instructions to finish. Once done, you should see the options available for Copy/Paste, folder share and others, as shown below
