Hello @user24837924 and welcome to :fedora: !

Could you please try to explain in more detail what you are trying to achieve, provide the output of the sudo rpm-ostree status command and the full Butane configuration you used to provision the machine. Also, is this bare metal, virtual machine, or cloud deployment?

Bootupd currently does not support RAID setups: Support updating multiple EFIs in mirrored setups (RAID) in bootupd · Issue #1485 · coreos/fedora-coreos-tracker · GitHub

Thanks,
is there a expected date, when updates will be possible with a RAID setup?
