Hi,
I experience this issue https://github.com/secureblue/secureblue/issues/1122#issuecomment-3480120077
The restorecon -Rv /var/lib/flatpak command doesn't do anything (empty output).
#[solved] flatpak-system-update.service returns error code

I fixed it with the following command as root:
flatpak --system repair
then:
systemctl reset-failed flatpak-system-update.service
systemctl start flatpak-system-update.service
systemctl status flatpak-system-update.service
No idea what the root cause was, but it's fixed.
