To acquire the [[VirtualBox/Recommended_Version|Recommended VirtualBox version]] tested with {{project_name_short}}, package <code>{{{virtualbox_package_debian}}}</code> should be installed from Debian [https://fasttrack.debian.net/ <code>fasttrack</code> repository] according to the following instructions. <ref>
This is {{kicksecure_wiki
|wikipage=Install_Software#Best_Practices
|text=non-ideal
}} but required since VirtualBox in unavailable in official Debian <code>{{Stable_project_version_based_on_Debian_codename}}</code> repository and difficult to install due to [[Dev/VirtualBox#VirtualBox_Installation_Challenges|VirtualBox Installation Challenges]].

Alternatively you could install VirtualBox from the [[VirtualBox/Other_Versions#Install_from_Oracle_Repository|Oracle (virtualbox.org) Repository]], but this comes with different [[Install_Software#Foreign_Sources|risks]]. VirtualBox might be updated by VirtualBox developers before being tested with {{project_name_short}} which could then lead to issues. (Described in footnote [[VirtualBox/Recommended_Version|Recommended Version]].)
