* Assuming you disable secure boot due to a package installation, even when you re-enable secure boot in your system configuration, you may still see [https://askubuntu.com/questions/726052/ubuntu-booting-in-insecure-mode-with-secureboot-enabled “Booting Booting in insecure mode” mode with SecureBoot enabled]
You'll always find a newer version of VirtualBox [https://www.virtualbox.org/wiki/Linux_Downloads using the Oracle ppa], so use that rather than the packaged version that comes with your distro. Warning: if you've already got VirtualBox installed from packages, you should remove it (but not 'completely' meaning don't destroy your existing images). Also, under packaged Ubuntu, you can simply <code>apt-get install virtualbox-guest-additions-iso</code>; however with the PPA, you'll need to download it yourself.
== Guest Additions ==
If you have problems with installing Guest Additions, see https://www.virtualbox.org/wiki/LinuxAdditionsDebug which describes what the drivers are, what they do, and how to install them manually.
<code>lsmod | grep vbox</code> will give you some info on what's installed; which will be different for the host and the guest.
<code>modinfo vboxdrv</code> will give you info about the specific driver; especially the filename and version. The version of the driver should match the version of VirtualBox that you're running.
== Extensions ==
You may need/want to install the "'''Extension Pack'''" for VirtualBox. That's because it provides USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption, and NVMe. First download the file (it's a tarball with a .vbox-extpack extension), and then use VBoxManage to install it.
<source lang="bash">
VBoxManage extpack listextpacks
VBoxManage extpack --help
VBoxManage extpack install --replace ~/Downloads/Oracle_VM_VirtualBox_Extension_Pack-5.2.13-122773.vbox-extpack
== Other Projects using VirtualBox ==

By providing automated creation and provisioning of virtual machines using Oraclethe default 'provider's VirtualBox (ed.: as well as other virtualization enginessystem), used by HashiCorp's [[Vagrant provides the tools to create and configure lightweight, reproducible, and portable virtual environments." http://www.vagrantup.com/]] * The MediaWiki project uses vagrant and provides instructions as well as the configuration itself so that you can setup a development instance in a snap.
