Problem
In Fedora Silverblue 36, a broken system update prevented Software from working properly. If you were unlucky and updated your system before it was fixed, you’ll not be able to use Software at all. The Explore and Installed sections will appear empty, and the Updates tab will show a top bar saying:
Operating System Updates Unavailable
Your operating system is no longer supported. This means that it does not receive security updates. It is recommended that you update to a more recent version.
Additionally, another error sometimes appear in the middle of the screen:
Error
cannot create temporary file: /var/cache/rpm-ostree/solv/(something)
Cause
rpm-ostree and libdnf, two underlying technologies, have a version mismatch and fail to cooperate. If you’re affected, you’ll have rpm-ostree-2022.8-1.fc36 installed. You can check your existing version in Terminal like this:
$ rpm -q rpm-ostree
rpm-ostree-2022.8-1.fc36.x86_64

Solution

$ rpm-ostree upgrade
and reboot.
