Can't download templates after upgrading to 4.1 (/etc/qubes-rpc/qubes.TemplateSearch doesn't exist)

User Support

Trying to install Fedora or Debian template, after upgrading to 4.1:

$ sudo qvm-template install fedora-37
[Qrexec] /bin/sh: 0: Can't open /etc/qubes-rpc/qubes.TemplateSearch
ERROR: qrexec call 'qubes.TemplateSearch' failed.

Which qube is running this and needs to have /etc/qubes-rpc/qubes.TemplateSearch file?

Is there a way to get that script manually somehow?

Also, after searching around, I tried to change /etc/yum.repos.d/qubes-r4.repo content so that the url points to r4.1 (in fedora-33 template). Then running in fedora-33 template:

% sudo dnf update --all

Installing updates in any of the qubes/templates never finishes, as described in Update through GUI never finishing - how to see logs? - #2 by crowphale

You need to use sudo qubes-dom0-update qubes-template-fedora-37 if you want to install the fedora 37 template.

4

Sounds like you are upgrading from an old installation. fc33 reached EOL 1 yr 5 mo ago. I would suggest do a full backup, and do a fresh install, then restore your VMs.

Frankly speaking, I don’t think it’s something easy to upgrade and continue using your fc33 template. After restoration, you’d better shift your App Qubes’ template to fc37 that’s shipped with Qubes R4.1.2.

qubes-dom0-update simply redirects any calls to qvm-template for
packages that start with qubes-template...
You may as well use qvm-template or qvm-template-gui directly

I never presume to speak for the Qubes team. When I comment in the Forum or in the mailing lists I speak for myself.

That gives the exact error I posted above.

Yes, I have old fedoras, but recently upgraded to Qubes 4.1 and that’s the problem that I don’t have more recent template or vm that would be compatible with Qubes 4.1 and that’s preventing me from downloading more recent fedora template.

8

Yes, but gives the same error as I posted above.

9

Yes, so backup and full reinstall will help.

Resolved by manually downloading the template from Index of /r4.1/templates-itl/rpm/ and then installing in dom0. Thanks to @51lieal help.

More info for anyone running into this issue:
When using qvm-template install <template_name>, the VM that is set as “Dom0 update qube” (can be changed in Global settings) needs to have the /etc/qubes-rpc/qubes.TemplateSearch file which wasn’t on old templates. Once you download one newer template and set it as dom0 update qube, you can use qvm-template install.
