As I have feared, the command seems to only be working with dnf on traditional desktops.
I could only advise at the moment to rollback to the working deployment (with rpm-ostree rollback), keep the system up to date and try again in a day or two. We might see if someone else on Silverblue has managed to upgrade to nvidia 570.xx on kernel 6.13.x.
Unfortunately I have no NVIDIA card, so can’t reproduce the issue myself.
Alternatively, in case you would want to try installing the NVIDIA drivers on an older deployment containing kernel 6.12.x, you can do a rollback by deploying a specific commit, as described in the docs[1], and then repeat the NVIDIA driver installation steps.
You would need to check when was it that kernel 6.13 landed in the stable repos, and deploy an image before that date. ↩︎
