I've reproduced this with the 6.3.0-7-generic kernel from mantic- proposed.

In my limited testing this worked with the 6.2.0-20.20 kernel, but not the 21.21 or 23.23 kernel. I have not yet tried any of the 6.3 kernels. I've only seen this on one host so far, howzit, which is an arm64 server. I have tested on three other arm64 servers and they don't appear to be impacted, so this could be some firmware issue. It adversely impacts maas installs and will cause a mantic install (which is using 6.2.0-21.21) to fail because it can't modify the boot paths. Here's what I see trying to remove a boot entry: ubuntu@howzit-kernel:~$ efibootmgr -v BootCurrent: 0005 Timeout: 5 seconds BootOrder: 0005,0007,0004,0006 Boot0004 UEFI: Built-in EFI Shell VenMedia(5023b95c-db26-429b-a648-bd47664c8012)..BO Boot0005* UEFI: PXE IPv4 Mellanox Network Adapter - 0C:42:A1:52:3D:4C PcieRoot(0x30000)/Pci(0x1,0x0)/Pci(0x0,0x0)/MAC(0c42a1523d4c,1)/IPv4(0.0.0.00.0.0.0,0,0)..BO Boot0006 UEFI: PXE IPv4 Mellanox Network Adapter - 0C:42:A1:52:3D:4D PcieRoot(0x30000)/Pci(0x1,0x0)/Pci(0x0,0x1)/MAC(0c42a1523d4d,1)/IPv4(0.0.0.00.0.0.0,0,0)..BO Boot0007* ubuntu HD(1,GPT,6d8df92f-72ad-4c24-bc8d-8236a4c5e222,0x800,0x100000)/File(\EFI\UBUNTU\GRUBAA64.EFI)..BO ubuntu@howzit-kernel:~$ sudo efibootmgr -B -b 0007 Could not delete variable: Invalid argument The same command will work with the 6.2.0-20.20 kernel.
