I’m using “mininum fedora 36” for raspi. I downloaded the lastest image,installed it and used it for a while and it was ok until I “dnf update” it. I received the following error in journalctl.

Strangely enough after the update if I started up the raspeberry pi without connecting to the monitor, the eth0 connection would failed. I had setup the system to use systemd-networked instead of NetworkManager and had uninstalled NetworkManager and it worked fine until the update to the latest kernel.
So what could be the problem and where can I report a bug for “mininum fedora 36 for raspi” ?
another issue :
How to solve this ?
fedora systemd-tmpfiles[439]: Detected unsafe path transition /var (owned by admin) → /var/cache (owned by root) during canonicalization of /var/cache.
Thanks…
