[Solved] Rawhide / F35 unable to upgrade

Current status of my installation:

$ rpm-ostree status -b

I tried to perform a upgrade on 11, Feb 10:00 UTC+8 and 22:00 UTC+8, and got the following error:

UPD: Solution

Tried this under the /etc/pki/rpm-gpg/ folder:

# ln -s RPM-GPG-KEY-fedora-35-primary RPM-GPG-KEY-fedora-35-x86_64

As $releasever becomes 35, edit /etc/yum.repos.d/fedora-cisco-openh264.repo, from




to prevent a 404 error (The above one is the default config for me after I rebase my silverblue from F33 to silverblue, it works before F34 was branched, but now I can only get a 404 error :rofl: ).
