Reinstall Qubes-Whonix™ Templates

How to Reinstall Qubes-Whonix Templates
Introduction
[edit]On occasion, it is necessary to reinstall a Whonix template from the Qubes repository. [1]
This chapter usually applies when the Template is:
- Outdated: To upgrade to a newer Point Release or a testers-only version of Whonix.
- Broken: Templates can become broken and/or unbootable for a number of reasons, such as when removing meta-packages that Whonix "depends" on to function properly, or after mixing packages
from a later Debian release. - Misconfigured: Not all Template modifications are easily reversible. In some cases, it may be necessary to reinstall the Template.
- Compromised: Users may suspect their Template has been compromised. For further information on this topic, see Indicators of Compromise.
- Testing: To ensure high quality of future Whonix releases by becoming a Whonix tester.
Warning
[edit]The reason is that any App Qubes based on the affected Template will inherit the same issues. Disregarding this advice could lead to serious consequences. For example, a core component of the Whonix security model depends on sys-whonix to force all traffic through Tor or block it. If sys-whonix is based on a Template with a misconfigured or broken firewall, the Whonix security model would be broken. [3]
Reinstallation Methods
[edit]Qubes has its own template reinstallation guide![]()
; however, this Whonix wiki entry should be preferred when reinstalling Qubes-Whonix Templates. The reason is that this guide is Whonix-specific and contains instructions on how to properly configure all settings. [4]
Use one of the following methods:
- A) Uninstall Qubes-Whonix and then Install Qubes-Whonix; OR
- B) Follow the Reinstall the Whonix template instructions below.
Reinstall the Whonix template
[edit]UpdateVM Setting
[edit]Since only Fedora-based UpdateVMs support the --action=upgrade option for reinstalling the Template, it is recommended that you create a dedicated Qubes dom0 UpdateVM based on Qubes' Fedora template. Forcing dom0 updates over Tor is still possible by setting sys-whonix as the NetVM for the UpdateVM. [5]
1. Create a new VM named dom0-updatevm.
Qubes VM Manager → VM → Create App Qube
- Name and label: Name the App Qube. Do not include any personal information (if the App Qube is compromised, the attacker could run
qubesdb-read /nameto reveal the VM name). Name the App Qube something generic, for example:dom0-updatevm. - Color: Choose a color label for the UpdateVM.
- Use this template: Choose the Fedora-based Template. For example:
fedora-42. (There may be a higher version number than34available than there was at time time of writing.) - Standalone: Leave the Standalone field unchecked.
- Type: Choose the type
App Qube. - Allow networking: Choose the desired NetVM from the list. For example:
sys-whonix. - Press:
OK.
2. Configure the NetVM setting of dom0-updatevm.
- Option A, clearnet updates: If non-torified, clearnet Qubes
dom0updates are preferred, then set the NetVM ofdom0-updatevm, for example, tosys-firewall.
Qube Manager → dom0-updatevm → Qube settings → Networking: sys-firewall → OK
[6]
- Option B, torified updates: If torified Qubes
dom0updates are preferred, then set the NetVM ofdom0-updatevmto Whonix-Gateway™.
Qube Manager → dom0-updatevm → Qube settings → Networking: sys-whonix → OK
[7]
3. The process of configuring the UpdateVM is now complete.
Update dom0
[edit]1 Launch a dom0 terminal.
Click the Qubes App Launcher (blue/grey "Q") → Open the Terminal Emulator (Xfce Terminal)
2 Upgrade Qubes dom0.
This step is mandatory. [9]
sudo qubes-dom0-update
3 Done.
The dom0 upgrade has been completed.
Configure salt using Qubes dom0 Community Testing Repository
[edit]Optional.
If you are an interested tester, click Learn More on the right.
The following command will configure Qubes dom0 salt to use qubes-templates-community-testing for downloading Whonix. [10]
sudo qubesctl top.enable qvm.whonix-testing pillar=true
The following steps to enable the qubes-templates-community-testing repository should no longer be necessary. Please report if these steps were necessary for you.
If you are an interested tester, click Learn More on the right.
1. Enable qubes-templates-community-testing repository.
View the Qubes Templates .repo![]()
file.
cat /etc/yum.repos.d/qubes-templates.repo
2. Ensure the file contains [qubes-templates-community-testing].
The following text should be included.
[qubes-templates-community-testing] name = Qubes Community Templates repository #baseurl = https://yum.qubes-os.org/r$releasever/templates-community-testing metalink = https://yum.qubes-os.org/r$releasever/templates-community-testing/repodata/repomd.xml.metalink enabled = 0 fastestmirror = 1 gpgcheck = 1 gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-qubes-$releasever-templates-community
3. Fix any missing sections.
If the [qubes-templates-community-testing] section is missing, then the user has probably already modified the file. In this case dnf [11] preserves user changes by saving updates to /etc/yum.repos.d/qubes-templates.repo.rpmnew [12] instead of overwriting the file. Since the .repo.rpmnew file is ignored by qubes-dom0-update, the .repo file must be manually updated.
Either:
- Manually add the changes from
.repo.rpmnewto the.repofile; or - Overwrite the
.repofile with the.repo.rpmnewfile:- sudo cp /etc/yum.repos.d/qubes-templates.repo.rpmnew /etc/yum.repos.d/qubes-templates.repo
- And then manually add back necessary changes. If the command fails because
/etc/yum.repos.d/qubes-templates.repo.rpmnewdoes not exist, then the user probably already has[qubes-templates-community-testing].
Reinstall
[edit]In the instructions below, a check is first made for a newer version of the Template.
- Upgrade if available: If a newer Template version exists, install it (
upgrade). - Reinstall if not: If no newer Template version is available, reinstall the existing version (
reinstall).
Unfortunately, there is no combined upgrade and reinstall command. [13]
1. Launch a dom0 terminal.
Click the Qubes App Launcher (blue/grey "Q") → Open the Terminal Emulator (Xfce Terminal)
2. Try to upgrade the Template.
- Requirement: This will only work if a new Point Release of the Template is available.
- Template choice: Replace
qubes-template-packagewith eitherqubes-template-whonix-workstation-17orqubes-template-whonix-gateway-17. - Testers: Replace
--enablerepo=qubes-templates-communitywith--enablerepo=qubes-templates-community-testingif you are a tester.
qvm-template --enablerepo=qubes-templates-community upgrade <qubes-template-package>
For example, to upgrade the whonix-gateway-17 Template:
qvm-template --enablerepo=qubes-templates-community upgrade whonix-gateway-17
For example, to upgrade the whonix-workstation-17 Template:
qvm-template --enablerepo=qubes-templates-community upgrade whonix-workstation-17
3. Check the command output. The following results are possible:
- Template was successfully upgraded: No further action required. Skip step four.
- No upgrade available: The Template is already the latest version. Proceed to step four to force a reinstall.
- Upgrade unsupported or failed: This may occur if your UpdateVM is not Fedora-based. Refer to UpdateVM Setting.
- Unexpected error: Could be caused by networking issues or repository problems. Investigate and retry as necessary.
4. Optional: Reinstall the Template.
- When to reinstall: If step two did not reinstall the Template (i.e. no new Point Release), you may force a reinstall here.
- Safety: Safe to run even if the Template is already up-to-date. It will simply be reinstalled.
qvm-template --enablerepo=qubes-templates-community reinstall <qubes-template-package>
For example, to reinstall the whonix-gateway-17 Template:
qvm-template --enablerepo=qubes-templates-community reinstall qubes-template-whonix-gateway-17
For example, to reinstall the whonix-workstation-17 Template:
qvm-template --enablerepo=qubes-templates-community reinstall qubes-template-whonix-workstation-17
- Template reinstalled successfully: Reinstallation completed without issues.
- Error during reinstall: Likely caused by connectivity problems or misconfiguration. Review the error message and retry.
Settings
[edit]Use salt to configure dom0 settings. [15]
sudo qubesctl state.sls qvm.anon-whonix
Optional Steps
[edit]Whonix Disposable Template
[edit]Qubes-Whonix Disposable Template can optionally be set up as a base for Disposables. [16]
In dom0, run.
sudo qubesctl state.sls qvm.whonix-workstation-dvm
Updates over Tor
[edit]Templates
[edit]To force all Template updates over Tor, use qubesctl in dom0. [17]
sudo qubesctl state.sls qvm.updates-via-whonix
To undo this setting, modify,
- Qubes R4.2:
/etc/qubes-rpc/policy/qubes.UpdatesProxy - Qubes R4.3:
/etc/qubes/policy.d/50-config-updates.policy
in dom0. [18] See also How-to: Fix dom0 Qubes-Whonix™ UpdatesProxy Settings.
dom0
[edit]To force dom0 updates over Tor, set Qubes' dom0 UpdateVM to sys-whonix. [19]
Qube Manager→System→Global Settings→Dom0 UpdateVM:sys-whonix→OK
To revert this change, set Qubes' dom0 UpdateVM to sys-firewall or another preferred VM. [20]
Qubes Manager→System→Global Settings→Dom0 UpdateVM:sys-firewall→OK
Enable AppArmor
[edit]AppArmor is enabled by default. No extra steps required.
Final Steps
[edit]Restart App Qubes
[edit]Any VMs based on the reinstalled Template must be restarted to reflect the updated file system.
Update and Launch Applications
[edit]Before starting applications in the Whonix-Workstation™ App Qube, update both Whonix-Gateway™ and Whonix-Workstation™ Templates.
To launch an application like Tor Browser:
Qubes App Launcher (blue/grey "Q")→Domain: anon-whonix→Tor Browser (AnonDist)
Done
[edit]The process of reinstalling Qubes-Whonix Templates is now complete.

If the
dom0UpdateVM is based on a Template that is broken or no longer trusted (the Template is broken, misconfigured, or compromised), an alternate UpdateVM can be used temporarily. In other words, more specifically, if the Whonix-Gateway Template (whonix-gateway-17) and/or its Whonix-Gateway ProxyVM (sys-whonix) are no longer trusted, then configure Qubesdom0to use a different UpdateVM by applying the following steps.
