Comment 87 for bug 1863434

I seem to have the same bug under Linux Mint 20.1 on a late 2008 MacBook.

After some upgrade a few months ago, I've got a [problem with shim-signed][1], where I was getting "Failed to set MokListRT" error and no GRUB menu. After purging shim-signed, the error messages were gone, but the GRUB menu did not come back.

I tried the solution linked to from comment #23, and it worked, but

(1) the menu does not look the same as before,

(2) there seem to be somewhat unusual timeouts before the menu is shown and after a boot option is selected, but I may be wrong.

The workaround suggested in comment #23 is to set

    GRUB_TERMINAL=console

in /etc/default/grub.
