WARNING: UEFI ESP partition not detected or configured

If you are using the fwupdmgr, you might have noticed the UEFI ESP partition not detected or configured -warning.

For us, it meant that the UEFI partition wasn’t labeled correctly and here is how to fix that.

First check all the partitions with the following command:

sudo blkid

You should see something like this:

/dev/nvme0n1p1: UUID="XXXX-XXXX" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="something"

Start gdisk with the following command:

sudo gdisk /dev/nvme0n1

• Press p to printout your partition table and verify your EFI partition.
• Press t to change type
• When asked for partition number, type the number of your EFI partition
• When asked the hex code, type: ef00.
• Press w to write changes and exit.
• Reboot.
