Error in templatesearcher

In Dom0 i can’t download templates. In Qubes Template Manager an error:
Failed to fetch template list. Error: [Errno 2] No such file or directory: ‘/etc/qubes-rpx/qubes.TemplateSearch’

I run Qubes on VM on Debian 12. VM resources: CPU 8 Memory 8.0 GiB Storage limit: 32 GiB (Used 11 GB)

First, running Qubes in a VM isnt supported, as you probably know.
But this error probably isnt related. It’s more likely due to the
template you are using for your update qube. What is that?

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