How to Reinstall a TemplateVM
|
|
=============================
|
|
|
|
If you suspect your [TemplateVM] is broken, misconfigured, or compromised, you
|
|
can reinstall any TemplateVM that was installed from the Qubes repository.
|
|
Starting in Qubes 3.1, the process is greatly simplified.
|
|
|
|
First, copy any files that you wish to keep from the TemplateVM's `/home` and
|
|
`/rw` folders to a safe storage location. Then, in a dom0 terminal, run:
|
|
|
|
$ sudo qubes-dom0-update --action=reinstall qubes-template-package-name
|
|
|
|
Replace `qubes-template-package-name` with the name of the *package* of the
|
|
template you wish to reinstall. For example, use `qubes-template-fedora-25` if
|
|
you wish to reinstall the `fedora-25` template. Only one template can be
|
|
reinstalled at a time.
|
|
|
|
Note that Qubes may initially refuse to perform the reinstall if the exact revision of
|
|
the template package on your system is no longer in the Qubes online repository. In
|
|
this case, you can specify `upgrade` as the action instead and the newer version will be
|
|
used. The other `dnf` package actions that are now supported in addition to `reinstall`
|
|
and `upgrade` are `upgrade-to` and `downgrade`.
|
|
|
|
**Reminder:** If you're trying to reinstall a template that is not in an enabled
|
|
repo, you must enable that repo. For example:
|
|
|
|
$ sudo qubes-dom0-update --enablerepo=qubes-templates-community --action=reinstall qubes-template-whonix-ws
|
|
|
|
**Note:** VMs that are using the reinstalled template will not be affected until they are
|
|
restarted.
|
|
|
|
|
|
Manual Reinstallation Method
|
|
----------------------------
|
|
|
|
If you're using Qubes 3.0 or older, you should use the manual reinstallation
|
|
method. You can also use this method on later Qubes versions if, for any reason,
|
|
you want to reinstall a template manually.
|
|
|
|
In what follows, the term "target TemplateVM" refers to whichever TemplateVM you
|
|
want to reinstall. If you want to reinstall more than one TemplateVM, repeat
|
|
these instructions for each one.
|
|
|
|
1. (Optional) Clone the existing target TemplateVM.
|
|
|
|
This can be a good idea if you've customized the existing template and want
|
|
to keep your customizations. On the other hand, if you suspect that this
|
|
template is broken, misconfigured, or compromised, you may want to remove it
|
|
without cloning it.
|
|
|
|
2. Create a temporary dummy template:
|
|
|
|
mkdir /var/lib/qubes/vm-templates/dummy
|
|
touch /var/lib/qubes/vm-templates/dummy/{root.img,private.img}
|
|
qvm-add-template dummy
|
|
|
|
3. Temporarily change all VMs based on the target TemplateVM to the new dummy
|
|
template, or remove them.
|
|
|
|
This can be a good idea if you have user data in these VMs that you want to
|
|
keep. On the other hand, if you suspect that these VMs (or the templates on
|
|
which they are based) are broken, misconfigured, or compromised, you may
|
|
want to remove them instead. You can do this in Qubes Manager by
|
|
right-clicking on the VM and clicking **Remove VM**, or you can use the
|
|
command `qvm-remove <vm-name>` in dom0.
|
|
|
|
Using a dummy template as a temporary template is preferable to using another
|
|
real TemplateVM because you can't accidentally boot any VMs from the dummy
|
|
template. (There is no OS in the dummy template, so the boot will fail.)
|
|
|
|
4. Uninstall the target TemplateVM from dom0:
|
|
|
|
$ sudo yum remove <template-package-name>
|
|
|
|
For example, to uninstall the `whonix-gw` template:
|
|
|
|
$ sudo yum remove qubes-template-whonix-gw
|
|
|
|
5. Reinstall the target TemplateVM in dom0:
|
|
|
|
$ sudo qubes-dom0-update --enablerepo=<optional-additional-repo> \
|
|
<template-package-name>
|
|
|
|
For example, to install the `whonix-gw` template:
|
|
|
|
$ sudo qubes-dom0-update --enablerepo=qubes-templates-community \
|
|
qubes-template-whonix-gw
|
|
|
|
6. If you temporarily changed all VMs based on the target TemplateVM to the
|
|
dummy template in step 3, change them back to the new target TemplateVM now.
|
|
If you instead removed all VMs based on the old target TemplateVM, you can
|
|
recreate your desired VMs from the newly reinstalled target TemplateVM now.
