Ideally for this testers wanted task, start fresh. Rename or delete both Whonix VMs sys-whonix and anon-whonix, reinstall whonix-gw and whonix-ws Qubes-Whonix templates. See the following instructions. Note: use
qubes-dom0-unstable rather than
qubes-templates-community then recreate Whonix VMs.
(The following command deviates from the above instructions so you install the testers rather than stable Whonix templates.)
sudo qubes-dom0-update --enablerepo=qubes-dom0-unstable qubes-template-whonix-gw qubes-template-whonix-ws
After template re-installation, to re-create Whonix VMs you can use the following command in Qubes dom0 using salt (not yet mentioned in Qubes documentation).
sudo qubesctl state.highstate
(Or you can also upgrade from Whonix jessie-proposed-updates and testers repository. Dedicated blog post and more information on this upgrade:
