[SOLVED] grub-mkconfig error

greembow · 2023-03-06 18:07:32

Hi, I was trying to enable hibernation on my laptop and after I added the resume kernel parameter, I tried to run grub-mkconfig like normal when I change kernel parameters, and it said something about an error on line 188. Previously, I attampted to use grub-customizer to add a submenu for memtest86+ and the UEFI Firmware Settings entries so they weren't in the main list. It gave me the same error, but I never really paid any attention to it, and assumed that memtest86+ just couldn't be put in a submenu. Now I'm getting that error using grub-mkconfig and I can't ignore it.

grub-mkconfig output

The only thing I can tell is that on line 188 in /boot/grub/grub.cfg.new, is that the UEFI Firmware Settings entry has been moved to a submenu when compared to the current file, like I described at the start of the post.
Other than that, I have no idea.

Did you remove grub-customizer? It set's up a config file that gets parsed by grub-mkconfig but is invalid with current grub versions

Just did and that fixed it. Thank you!
