Upgrading Ubuntu from 17.04 to 17.10

In June of 2017 I upgraded my Ubuntu 16.10 (Yakkety Yak) LTS install to Ubuntu 17.04 (Zesty Zapus). In October of 2017 Ubuntu released 17.10. (Artful Aardvark).

How to Install VirtualBox Guest Additions in Security Onion 14.05

After having to piece together a VirtualBox Guest Addition installation method from some old articles, I decided to put together one for Security Onion 14.05.

Once you have Security Onion 14.05 installed and running, start the Terminal Emulator and walk through the following commands, one-by-one:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo shutdown -r now

After the reboots, launch the Terminal Emulator and run the following commands:

sudo apt-get install build-essential module-assistant dkms
sudo add-apt-repository universe
sudo apt update
sudo m-a prepare

In the virtual machine window, select Devices > Insert Guest Additions CD image…

cd /media/%username%/VBOXADDITIONS (tab complete)
sudo ./VBoxLinuxAdditions.run
sudo shutdown -r now

After the reboot, the VirtualBox Guest Additions should be installed and all features should be available.

As a last step, select Devices > Optical Drives > Remove disk from virtual drive…
