I faced this, but not on a Mac. I have an ordinary Desktop PC with a Gigabyte 880GM-USB3 (rev3.1) motherboard. This old motherboard does not have secure boot or MokManager or UEFI etc. It has a legacy BIOS. I installed Ubuntu 20.10 (Groovy Gorilla) yesterday. Each time I start the PC, I'm shown the following message for around 10 seconds and only then it proceeds to grub: Failed to set MokListRT: Invalid Parameter Could not create MokListRT: Invalid Parameter Importing MOK states has failed: import_mok_state() failed: Invalid Parameter Continuing boot since secure mode is disabled System BootOrder not found. Initializing defaults. Creating boot entry "Boot0002" with label "ubuntu" for file "\EFI\ubuntu\shimx64.efi" Failed to set MokListRT: Invalid Parameter Could not create MokListRT: Invalid Parameter Import MOK states has failed: import_mok_state() failed: Invalid Parameter Continuing boot since secure mode is disabled.
I've attached an image of the error screen. The annoying thing about this bug is that each time I start my PC, this message is shown for 10 seconds. Please fix this. Many people still use old computers that don't have MokManager etc. Please take that into account. ** Attachment added: "Failed to set MokListRT: Invalid Parameter" https://bugs.launchpad.net/ubuntu/+source/shim/+bug/1867092/+attachment/5494299/+files/startupError -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867092 Title: Failed to set MokListRT: Invalid Parameter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1867092/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
