It is strongly advised to use the recommended VirtualBox version with Kicksecure ™, otherwise there can be issues. [1]

Info Recommended VirtualBox version.

  • Linux Tux.png: please press expand on the right side.

info Recommendations for Linux users:

  • The recommended host Linux kernel version is the same version that Debian bullseye is using, see linux-image-amd64.
  • Linux users only: use the recommended Linux distribution as a host for Kicksecure ™ VirtualBox is Debian Linux version bullseye.

Hosts using a non-Debian OS: Tux.png

Install VirtualBox as per the normal mechanism for your Linux distribution. Kicksecure ™ has has been tested with, expects VirtualBox version latest

For example VirtualBox version 5.2.18 has been reported to not be compatible.

Ubuntu hosts: Logo-ubuntusvg.png

Ubuntu bionic (18.04LTS) APT repository ships only VirtualBox version 5.2.18 and Kicksecure ™ will probably not work.

You might want to release-upgrade to Ubuntu hirsute (21.04) and install the virtualbox package from the hirsute-updates backports repository which provides at time of writing VirtualBox version 6.1.26.

  • These instructions are for host operating systems running Debian bullseye, which is recommended.
  • Other Debian releases might work, but this is untested.
  • To acquire the Recommended VirtualBox version tested with Kicksecure ™, package virtualbox should be installed from Debian fasttrack repository according to the following instructions. [2]

1. On the host.

Open a terminal.

2. Add Debian the fasttrack repository.

Update the package lists.

sudo apt update

Install the Debian fasttrack signing key.

sudo apt install fasttrack-archive-keyring

Add the Debian fasttrack repository.

echo 'deb bullseye-fasttrack main contrib non-free' | sudo tee /etc/apt/sources.list.d/fasttrack.list

3. Update the package lists again. [3]

sudo apt update

4. Install VirtualBox and Linux kernel headers.

sudo apt install virtualbox linux-headers-$(dpkg --print-architecture)

5. Add your current user to group vboxusers. [4]

sudo adduser $(whoami) vboxusers

6. Done.

The procedure of installing the VirtualBox host software is complete.

  1. Kicksecure ™ was built and tested with VirtualBox version latest. Newer VirtualBox versions not listed on the stable version of Kicksecure ™ for VirtuallBox, testers-only version of Kicksecure ™ for VirtuallBox or otherwise in Kicksecure ™ News are untested by Kicksecure ™ developers. This can cause issues such as instability (VirtualBox VMs not starting, VMs suddenly closing, host freezing, VM black screen). It is advised to wait until newer versions of VirtualBox are recommended for use with Kicksecure ™.

    Newer VirtualBox versions are hard to install on Debian bullseye. Perhaps the VirtualBox host software is available (even as a Debian package) from the repository, but VirtualBox guest additions are not available as a Debian package. Using an older version of VirtualBox guest additions (like the pre-installed ones) might lead to broken functionality such as an inability to resize the VM or general instability. Installation of VirtualBox guest additions from ISO might also cause issues.

  2. This is non-ideal but required since VirtualBox in unavailable in official Debian bullseye repository and difficult to install due to VirtualBox Installation Challenges. Alternatively you could install VirtualBox from the Oracle ( Repository, but this comes with different risks. VirtualBox might be updated by VirtualBox developers before being tested with Kicksecure ™ which could then lead to issues. (Described in footnote here.)
  3. This is to acquire the Debian fasttrack repository package sources.
  4. Optional: See: Also spams ~/.config/VirtualBox/VBoxSVC.log log if not done.
