"error: No installed package matches 'firefox'", when rebasing on a system without firefox

[czhang03]

Describe the bug

I started with a base that contains firefox, specifically silverblue-nvidia image from ublue. Then I removed firefox, and rebased onto a base without firefox, specifically silverblue-nvidia-userns-hardened from secureblue.

Then everytime I try to run ostree command it fails with the following error:

> rpm-ostree kargs --append-if-missing="init_on_alloc=1"
Checking out tree 4b1eed3... done
error: No installed package matches 'firefox'

rpm-ostree status looks fine:

Reproduction steps

Here is my guess, I will test this later:

1. start with silverblue-nvidia image from ublue (personally I installed via iso)
2. remove firefox and firefox langpack
3. rebase onto silverblue-nvidia-userns-hardened from secureblue (personally, I rebased directly onto the signed image: rpm-ostree rebase ostree-image-signed:docker://ghcr.io/secureblue/silverblue-nvidia-userns-hardened:latest)

Expected behavior

ostree command would run

Actual behavior

ostree command fail with error message: error: No installed package matches 'firefox'

Additional information

Attempt Fix: Layering Firefox

layering firefox is not possible, as secureblue removed firefox from repo:

$ rpm-ostree install firefox
error: Cannot request 'firefox' provided by removed package 'firefox-122.0-1.fc39.x86_64'

Attempt Fixes: Go Back, Reser, Re-rebase

I rebased back to silverblue-nvidia image, reset all the override:

rpm-ostree override reset --all

And rebased back to silverblue-nvidia-userns-hardened image, and ostree worked like a charm. I used the signed repo for both rebase.

Try rpm-ostree reset firefox firefox-langpacks ?

[czhang03]

As I mentioned in the original issue, rebase back to the original base and reset works. But I don't think (I recalll I have tested this, but I don't feel like testing it at this momnet) resetting on the current base (the base that doesn't include firefox) works.
