hi guys

I’ve one box where I just yesterday upgraded CentOS. I
wonder if that kernel upgrade process might somewhat troublesome. After that upgrade UEFI boot fails with:

Failed to set MokListRT: Invalid Parameter Something has gone seriously wrong: import_mok_state() failed
: Invalid Parameter

Has anybody seen that? And maybe know to fix it?
many thanks, L.

  • We have updates dozens of Dell servers with that kernel/grub2 combo. That doesn’t mean there might not be an issue with something though .. but as far as we can tell. Secureboot and UEFI both work OK on our machines.

  • Hi,

    Not locked by me, but Red Hat.

    The email is similar to report I made.

    You may wish to use an older kernel possibly.

    Also there is a reference to downgrading shim via article:

    https://access.redhat.com/solutions/3683241

    Not tried either of the above as I can live with errors I get and boot system.

  • I don’t know if it’s related, but all of our dual-boot workstations that used rEFInd for the boot selector stopped being able to launch the shim EFI executable after upgrading to the 7.6 shim. I had to manually change the refind configuration to point at the GRUBX64 EFI
    executable instead (we turn off secure boot anyway, custom kernel modules).

  • No rEFInd on my old iMac 2008 (well, my wife’s computer at home) but I
    had myself to boot in rescue and copy grubx64.efi as shimx64.efi to have the iMac to boot again (exclusively running CentOS 7)
    I initially thought about a very old Apple firwmare (so incompatible with shim v15) but if people on the list are reporting that for Dell servers, I guess that it’s not a good sign
