How to uninstall Qubes-Whonix.

Introduction[edit]

This procedure of a complete uninstallation of Whonix™ as documented on this page is useful before a complete re-installation of Qubes-Whonix. [1]

Alternatively, it is possible to Reinstall Qubes-Whonix Templates without a complete a uninstallation.

In any case, these procedures are unspecific to Whonix.

  • In some situations qvm-templatearchive.org with the purgearchive.org instead of the removearchive.org subcommandarchive.org might be simpler.
    • remove:

      Remove installed templates.

    • purge:

      Remove installed templates and associated VMs.

Users can replace Whonix version 16 with 17 or any other version number if that is the goal.

Purge[edit]

Data loss possible if used wrong! Before proceeding with the qvm-template purge the user should carefully review the output of the qvm-template command before confirming. In doubt, a different method as document in other chapters should be used.

Might not work due to Qubes issue qvm-template purge whonix-gw-16 results in ERROR: The dummy qube does not provide networkarchive.org.

1. Shutdown required App Qubes.

Shutdown of all Whonix App Qubes is required that are using whonix-gateway-17 or whonix-workstation-17 as a Template or Net Qube

2. App Qubes Configuration

If no App Qubes that the user intents to keep are using whonix-gateway-17 or whonix-workstation-17 as a Template or Net Qube, proceeding with qvm-template purge should be safe.

3. Purge Whonix-Gateway™

qvm-template purge whonix-gw-17

4. Review the output.

Sample output:

This will completely remove the selected VM(s)... 
 whonix-gateway-17
 sys-whonix
 anon-whonix
 whonix-workstation-17-dvm
 custom-vm-using-whonix-workstation-17-template
Are you sure? [y/N]

5. Confirm or abort.

To proceed, a capital (big lettter) Y needs be be written and confirmed with enter.

6. Purge Whonix-Workstation™

qvm-template purge whonix-ws-17

Whonix-Workstation Removal[edit]

Remove Whonix-Workstation App Qubes[edit]

The anon-whonix Whonix-Workstation App Qube [2] must be manually removed. Alternatively, you can Stop using Whonix Templates in VM Template Settings.

If anon-whonix was previously used, strongly consider backups of any important files before proceeding.

1. Remove anon-whonix.

  • Qube Manager → right-click Whonix App Qube anon-whonix → Delete qube [3]

2. Repeat the above step for any other App Qubes based on Whonix-Workstation Template whonix-workstation-17 that were created earlier. Replace vm-name with the actual name of the VM.

  • Qube Manager → right-click Whonix App Qube vm-name → Delete qube [4]

Remove the Whonix-Workstation Disposable Template[edit]

The whonix-workstation-17-dvm domain must be manually removed. Alternatively, you can Stop using Whonix Templates in VM Template Settings.

In the case of a customized Whonix-Workstation Disposable Template, strongly consider backups of any important files before proceeding.

Launch a dom0 terminal.
Click the Qubes App Launcher (blue/grey "Q") → Open the Terminal Emulator (Xfce Terminal)

1. Set the default Disposable for anon-whonix to "". This is only required if you chose to skip removal of anon-whonix as documented above.

qvm-prefs anon-whonix default_dispvm ""

2. Repeat the above step for all other App Qubes that are based on Whonix-Workstation Template whonix-workstation-17 that were created earlier. Replace vm-name with the actual name of the VM.

qvm-prefs vm-name default_dispvm ""

3. Set the default Disposable for whonix-workstation-17-dvm to "".

qvm-prefs whonix-workstation-17-dvm default_dispvm ""

4. Remove whonix-workstation-17-dvm.

qvm-remove whonix-workstation-17-dvm

5. The process of removing whonix-workstation-17-dvm is now complete.

Whonix-Gateway Removal[edit]

Stop using Whonix-Gateway as Qubes UpdateVM[edit]

Set Qubes dom0 UpdateVM to sys-firewall or any VM of your choice.

Note: Upgrades will be no longer torified.

This is only required if you previously elected to update dom0 through Whonix. Regardless, it is a good idea to check the Qubes dom0 UpdateVM setting.

  • Qubes Manager → System → Global Settings → Dom0 UpdateVM: sys-firewall → OK [5]

Stop using Whonix-Gateway as NetVM for any VM[edit]

If you configured any VM to use sys-whonix as NetVM, this change must be undone.

Note: The VM's traffic will be no longer torified.

This is only required if you previously elected to torify a VM's network traffic through Whonix. Regardless, it is a good idea to check the NetVM setting of Qubes VMs.

To set the NetVM of any VM to None, in other words, to disable networking.

Qube Manager → right-click vm-name → Qube settings → NetVM → None → OK [6]

Alternatively, you can set the NetVM to sys-firewall or another ProxyVM of your choice. However, traffic will not be torified (unless you are using cloned VMs).

Remove Whonix-Gateway ProxyVMs[edit]

The sys-whonix Whonix-Gateway ProxyVM [2] must be manually removed. Alternatively, you could Stop using Whonix Templates in VM Template Settings.

In the case of a previously used sys-whonix ProxyVM, consider backups before proceeding. This might be a custom Tor configuration, Onion Services configuration, Bridges configuration or Tor data for persistent Tor Entry Guards.

1. Remove sys-whonix.

  • Qube Manager → right-click sys-whonix → Delete qube [7]

2. Repeat the above step for any other ProxyVM based on Whonix-Gateway Template whonix-gateway-17 that was created earlier. Replace vm-name with the actual name of the VM.

  • Qube Manager → right-click vm-name → Delete qube [8]

Qubes Adjustments[edit]

Stop using Whonix Templates in VM Template Settings[edit]

If a Whonix Template is set as the underlying Template for any VMs, the Template cannot be removed. Therefore, either delete the VM as documented above or unset the Template using Qube Manager. [9]

The VMs can optionally be set to use a dummy template. The advantage of setting a dummy template as the underlying Template is the ability to retain any VMs, along with the user storage contents.

1. Create the dummy Template. [10]

Launch a dom0 terminal.
Click the Qubes App Launcher (blue/grey "Q") → Open the Terminal Emulator (Xfce Terminal)

Execute the following commands.

qvm-create --class Template --label red dummy

Unspecific to Qubes-Whonix™.

The process of creating the dummy Template is now complete.

2. Shut down the Whonix Template if already running.

  • Qube Manager → right-click Whonix Template → Shutdown qube [11]

3. Set the dummy template as the Template.

  • right-click VM → Qube settings → Template: dummy [12]

The process of setting the dummy template as the VM's underlying Template is complete.

Stop using Whonix-Gateway for Torified Template Updates[edit]

Info Skip this chapter if you intend to Install Qubes-Whonix again.

If you do not intend to use Qubes-Whonix again, apply the following steps.

In technical terms, stop using Whonix-Gateway as dom0 UpdatesProxy for any Templates. This is only required if you previously elected to update Qubes Templates through Whonix.

1. Open /etc/qubes-rpc/policy/qubes.UpdatesProxy with root rights.

2. Search for.

$type:Template $default allow,target=sys-whonix

3. Comment out that line; add a hash (#) in front of it.

#$type:Template $default allow,target=sys-whonix

[13]

4. Save.

5. The steps to remove Whonix-Gateway as dom0 UpdatesProxy are complete.

Footnotes[edit]

  1. ↑ Or if deciding not to use Whonix™ at all.
  2. ↑ 2.0 2.1 Qubes glossaryarchive.org documents TemplateBasedVM, TemplateBasedVMs and TemplateBasedHVM. So the spelling of TemplateBasedAppVMs and TemplateBasedProxyVMs should be correct.
  3. ↑ qvm-remove anon-whonix
  4. ↑ qvm-remove vm-name
  5. ↑ To revert this change, run. qubes-prefs updatevm sys-firewall
  6. ↑ qubes-prefs --set vm-name netvm ""
  7. ↑ qvm-remove sys-whonix
  8. ↑ qvm-remove vm-name
  9. ↑ Or use the command line.
  10. ↑
  11. ↑ qvm-shutdown vm-name
  12. ↑ qvm-prefs --set vm-name template dummy
  13. ↑ The entry $tag:whonix-updatevm $default allow,target=sys-whonix and $tag:whonix-updatevm $anyvm deny can remain. These will not have any effect once Qubes Templates are removed since no VM has the tag whonix-updatevm.
  14. ↑ 14.0 14.1 14.2 Note the matching syntax below and the effect of running qubes-template-whonix-gw* or qubes-template-whonix-w**. Also note the asterisk * wildcard at the end. Depending on the Whonix version, this leads to multiple template packages being uninstalled if they are present:
    • qubes-template-whonix-gw-15 (deprecated Whonix release)
    • qubes-template-whonix-ws-15 (deprecated Whonix release)
    • qubes-template-whonix-gw-16 (stable Whonix release)
    • qubes-template-whonix-ws-16 (stable Whonix release)
    • qubes-template-whonix-gw-17 (future Whonix release)
    • qubes-template-whonix-ws-17 (future Whonix release)
    Wildcards are used so these instructions are valid for all old and future versions of Whonix. Alternatively, the asterisk * syntax could be replaced with a specific template package listed above.
