BIOS update for Proxmox 9 hosts not working

[metcon]

Hi, I recently successfully updated Proxmox to version 9. My Proxmox hosts are Dell Optiplex 3080 micro PCs.

Previously, under version 8, I updated the BIOS of the PCs via fwupdmgr. Therefore, I had modified the file /etc/fwupd/daemon.conf with the following contents:

[fwupd]
EspLocation=/boot/efi

This worked perfectly.

I now notice with the new version of Proxmox that I can create and modify the daemon.conf file, but that the changes are not retained.

I get the following error message:

fwupdmgr get updates
WARNING: UEFI ESP partition not detected or configured.

Is it still possible to update the BIOS of a Proxmox 9 host in this way? If not, what are other ways?

Thanks for the help.

Thanks for the info. We'll have to wait for a solution as far as I can tell.
