State of RPM Fusion in Silverblue during upgrade / rebase

Hi!
I wanted to understand the state of Third party repositories (RPM Fusion, but also eventually other third party repos eg Skype) during an upgrade of Silverblue (33 to 34 eg).
In workstation that is very polished.
Is that similar on Silverblue?

Maybe there are some special tricks in that regard - but I must admit that I do have trouble doing rebase due to RPM Fusion. Unfortunately the main documentation only covers rebasing when using straight fedora repos.

So overall how is the situation?
Does third party repo have to be removed before upgrade???

Just recently I found something that makes rebaseing to me really easy:

  1. First of: you need to remove the rpm-fusion repos. This might look like %1 below.
  2. In case a rebase is not possible due to conflicts through packages you installed from rpmfusion, you can just factory reset your current installation %2. This is probably not a great deal especially if you use toolbox a lot.
%1 $ rpm-ostree rebase fedora:fedora/33/x86_64/silverblue --uninstall=rpmfusion-nonfree-release-32-1.noarch --uninstall=rpmfusion-free-release-32-1.noarch
%2 $ rpm-ostree reset

All of this makes it pretty easy to jump in between fedora versions. 5 days ago I was using rawhide, in a matter of just a few minutes I switched to fedora 32 and again just a few minutes later I switched to fedora 33 without any problems.

To me this only leaves the matter of groupupdate in case of Multimedia. rpm-ostree doesn’t seem to support groupupdate, currently I just use a fedora container to figure out the dependencies I want to install like:

$ podman run -it --rm fedora:33 bash
[root@88864240c6fc /]# dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

Thanks for your answers!
That was very instructive.
So overall for example upgrading (graphically with gnome software lets say) from FSilverblue 33 to 34 will fail if i have rpmfusion enabled on the system?

I’m glad if can help.

The chances are high that a direct upgrade fails yeah, but either way you need to do the upgrades via CLI because rpm-ostree isn’t integrated into Gnome Software, yet.

Whenever that fails you can use rpm-ostree status in order to identify which packages you installed (aka layered) into your system and use that is base to manage those packages in future versions. This looks like the following on my machine:
