How to Reinstall a TemplateVM
|
|
=============================
|
|
|
|
If you suspect your [TemplateVM] is broken, misconfigured, or compromised,
|
|
or if you wish to do a clean reinstall in order to upgrade to a new version, you
|
|
can reinstall any TemplateVM from the Qubes repository. In what follows, the
|
|
phrase "target TemplateVM" refers to whichever TemplateVM you want to reinsatll.
|
|
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.
