The GNOME Software application appears to have lost its repository configuration. I recall, from the fedora 36 release notes, that package configuration has moved from /var to /lib and I wonder if it’s related to that. The problem seemed to arise with gnome-software-42.1.
Until the problem is fixed you can update your flatpaks with “flatpak update” and your OS image and layered packages with “sudo rpm-ostree upgrade” in a terminal.
I did my rpm-ostree upgrade in the terminal, and that went fine, but my GNOME Software is not working, just like the others in this thread:
I just rebooted and got that exact same error too. Is there some issue or thread where to track progress of this? Not being able to add/remove/update software (graphically) is not nice 
I get the same error… I’m kinda new to silverblue so I was thinking I’ve done something wrong but it seems to be broken everywere…
I guess It will be fixed soon… Until then just uptade with rpm-ostree upgrade and flatpak update and well installation are also in CLI I guess until there is a fix.
I’ve found a temporary “workaround”:
sudo chmod 757 /var/cache/rpm-ostree/solv/
This gives everyone write access to this directory, whereas it used to be limited to root. Do this at your own discretion and accept the possible risks that comes with that.
This looks to be the best place to track it for now: https://bugzilla.redhat.com/show_bug.cgi?id=2083715
Edit: Note that rpm-ostree upgrade command is unaffected. So if you want to, you can use the command line to manage your system instead of the GUI in the meantime.
Thanks for the bug report link. Now we can follow along as this gets fixed.
Thanks. There it also explains the workaround we can apply as this gets fixed:
rpm-ostree override replace https://bodhi.fedoraproject.org/updates/FEDORA-2022-7a894b6507
systemctl reboot
Thanks for the tip. But as you warned, perhaps is better to keep using the command prompt for the time being and keep security in place.
Yep, I can confirm this command works. It downgraded the offending library and now all seems back to normal, after a reboot of course.
The fix has been moved to stable:
https://bodhi.fedoraproject.org/updates/FEDORA-2022-af207692d6
To get it, just do a regular rpm-ostree update in the terminal:
$ rpm-ostree update
$ systemctl reboot
When the system rebooted, my GNOME Software was working.
I think I need to wait a little bit. Just did an update and the issue remains. 
Perhaps I did something wrong. This is the output I get, either using rpm-ostree update or rpm-ostree upgrade:
rpm-ostree upgrade

No upgrade available
Not sure if this is related, but now GNOME Software is working again, but this update of the RPMFusion repos persists. Updating via GNOME Software doesn’t apply it, and it doesn’t show when doing rpm-ostree update:
I tried to remove the “old” RPM Fusion repos and then reinstall, but that didn’t work. Terminal output was that ffmpeg and ffmpeg-libs were unavaliable.
To fix what I broke, I rolled back to my previous version:
$ rpm-ostree rollback
I checked on ffmpeg and I am running the latest version, so all good for now.
Side-note, as I guess may be related and you still have that “harder” setup: You can simplify rpmfusion updates, like to Fedora 36 a lot, so you don’t need to uninstall and reinstall the rpmfusion repos etc. (That may also fix your upgrade issue there.)
I had to modify the code from Fedora Discussion so it works for Fedora Silverblue 36 users who upgraded from 35.
Before you run the command, confirm the version of the RPM Fusion repos you need to uninstall by running:
rpm-ostree status
Once I did that, I knew how to modify this code before running it in the terminal:
rpm-ostree update \
--uninstall rpmfusion-free-release-36-0.2.noarch \
--uninstall rpmfusion-nonfree-release-36-0.2.noarch \
--install rpmfusion-free-release \
--install rpmfusion-nonfree-release
After a reboot, this cleared up the issue with RPM Fusion repo updates in GNOME Software.
I was able to fix my issue following comment #24, here:
https://bugzilla.redhat.com/show_bug.cgi?id=2083715
That fixed one problem for me, but now I have 2088878 – Silverblue: Failed to create file ?/var/run/dnf-metadata.lock.9ONHM1?: Permission denied and still I cannot use gnome-software. I also get 2088879 – rpm-ostree update gets stuck when using rpm-ostree by terminal.
So, basically, I cannot update. No way.
