Couldn't find EFI system partition.

[DSI_FA]

Ever since I upgraded from PMG 8 to PMG 9.1.2, I get the following message whenever I run an update:

Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.

Please post your /etc/fsab, there should be a mount entry like this:

UUID=XXX-XXXX /boot/efi vfat defaults 0 1

And the output of these two:

lsblk -o +fstype
[ -d /sys/firmware/efi ] && echo UEFI || echo BIOS

It seems that you do not have a EFI because your server is in Legacy mode.
You can just ignore the message or change in BIOS to UEFI mode an reinstall the system.

That's what I thought, but I wanted to make sure it wouldn't affect the system or future updates.

It's not an urgent problem right now. UEFI is a most secure boot than Legacy, but linux can work on both. I don't know if it will be a requirement on next Proxmox versions, but I doubt it. Still, I would consider switching to UEFI when you have to upgrade to Proxmox 10 for security reasons.
