In this article, we will explain how to install VirtualBox Guest Additions on Ubuntu and Debian based distributions such Linux Mint.
How to Install VirtualBox Guest Additions in Ubuntu
1. First start by updating your Ubuntu guest operating system software packages using following command.
$ sudo apt update $ sudo apt upgrade
2. Once upgrade completes, reboot your Ubuntu guest operating system to effect the recent upgrades and install required packages as follows.
$ sudo apt install build-essential dkms linux-headers-$(uname -r)
3. Next, from the Virtual Machine menu bar, go to Devices => click on Insert Guest Additions CD image as shown in the screenshot. This helps to mount the Guest Additions ISO file inside your virtual machine.

4. Next, you will get a dialog window, prompting you to Run the installer to launch it.

5. A terminal window will be opened from which the actual installation of VirtualBox Guest Additions will be performed. Once the installation is complete, press [Enter] to close the installer terminal window. Then power off your Ubuntu guest OS to change some settings from VirtualBox manager as explained in the next step.

6. Now to enable Shared Clipboard and Drag’n’Drop functionality between Guest and Host Machine. Go to General => Advanced and enable the two options (Shared Clipboard and Drag’n’Drop) as you wish, from the drop down options. Then click OK to save the settings and boot your system, login and test if everything is working fine.

Congratulations! You have successfully installed VirtualBox Guest Additions on Ubuntu and Debian based distributions such Linux Mint.

I am usually running Win 10 Pro Edition…
I’m running ubuntu VirtualBox on a mac os x (Mojave) everything works fine but I can’t paste the content into the machine and I can’t copy from it and vice versa. I’ve installed and uninstalled guest additions like 5x and all my settings are set to bidirectional. I’m 10 seconds from giving up entirely because I can’t do this. PLEASE help.

@doc-please delete my first comment I wasn’t thinking and accidentally signed it with my son’s name while I was talking to him
I’m using Ubuntu 20.04 and Guest Additions with VirtualBox 6.0 on Windows 10. I can change the Ubuntu resolution (to any of around 12 or so options) and it looks great.
However, it doesn’t stay set from session to session. I’ve tried various recommendations I’ve found online, but none work. What are the top 5 or so things to (re)check and/or try? I’m hoping it’s just a checkbox or something simple like that.
I had the same issue, Ubuntu 20.04, Guest Additions with VBox 6.0 on Win 10.
Thanks for your help. I got all set to start using my Ubuntu 20.04 ID_Like=Debian.
Thank you, Sir! With your help, I was able to have a full screen on virtual box Linux Ubuntu on Windows 10.

You are most welcome, we are glad that this article helped you. Thanks for the feedback.
I think it would be a good idea to write the command correctly:
$ sudo apt install build-essential dkms linux-headers - $ (uname -r) INCORRECT SYNTAX
$ sudo apt install build-essential dkms linux-headers-$(uname -r) CORRECT SYNTAX

True, let’s review the article and correct it.
When I try to click insert guest additions cd image, it says Unable to insert the virtual optical disk
C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso
into the machine Ubuntu 2020.Could not mount the media/drive ‘C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso’ (VERR_PDM_MEDIA_LOCKED).
If you check your VirtualBox settings, under storage. There is already a VirtualBox guest additions ISO listed there, so the Device-> Insert will fail with that lock message. To solve this, ignore the Device-> Insert, and open your File Manager instead, then run the VirtualBox shell that installs the guest addition. Another option is to remove the ISO from the settings and start your ubuntu, then use the Device-> Insert.

Wonderful! Many thanks for sharing.
