Why doesn’t Qubes Template manager have access to all of the .rpm images
hosted on the QubesOS FTP server?
If you want to install testing templates then you need to enable testing templates repositories in Qubes Global Config → Updates tab.
I’ve done this already, but I don’t see all of the available repos.
What is missing?
For example, it doesn’t list all of the .rpm images listed in this directory:
https://ftp.qubes-os.org/repo/yum/r4.2/current-testing/vm/fc39/rpm/
That repository contains packages that can be installed in fedora-39 template.
The Qubes Template Manager is not a tool to install packages inside the templates, it’s to manage the templates themself in dom0 - Install/reinstall/downgrade/upgrade templates etc:
Is Fedora Atomic image available? This would be useful because you could rebase
to secureblue.
No
I never presume to speak for the Qubes team.
When I comment in the Forum I speak for myself.
