### Qubes 4.0.1 Warning ### Welcome to the Qubes OS installation guide!
This guide will walk you through the process of installing Qubes.
<div class="alert alert-danger" role="alert"> Please read it carefully and thoroughly, as it contains important information for ensuring that your Qubes OS installation is functional and secure.
<i class="fa fa-exclamation-circle"></i>
<b>Attention : </b> For those using Debian and Whonix templates, a vulnerability affects the latest stable Qubes OS release. Follow the instructions below to fix it.
</div>
<p>Immediately after installing Qubes 4.0.1, upgrade all of your Debian and Whonix TemplateVMs by executing the following commands in a dom0 terminal:</p>
$ sudo qubes-dom0-update --action=upgrade qubes-template-debian-9
$ sudo qubes-dom0-update --enablerepo=qubes-templates-community --action=upgrade qubes-template-whonix-gw-14
$ sudo qubes-dom0-update --enablerepo=qubes-templates-community --action=upgrade qubes-template-whonix-ws-14
These upgrades are required in order to be protected from the APT update mechanism vulnerability that was announced
and patched in [QSB #46], which followed the release of Qubes 4.0.1.
This method is simpler than the method recommended in [QSB #46], and it is just as safe/effective as long as it is performed immediately after installing Qubes OS.
