Grub error: symbol ‘grub_is_lockdown’ after update
by Motte from LinuxQuestions.org on (#5FJH8)
Hi there,
I hope I'm posting in the right section.
when booting my system goes into grub rescue mode with the message
Code:error: symbol grub_is_lockdown' not foundWhat happened:
Recently I updated grub after reading this article: https://forum.manjaro.org/t/grub2-se...ommended/57280.
I'm using an EFI system so I followed the instructions in the corresponding section. No errors occurred so I went on to activate the os-prober because I have a dual boot system (Manjaro and Windows).
Now grub rescue mode shows up with the error message I mentioned above. I found this tutorial:

which I followed closely but when I enter
Code:insmod normalit only shows the same message:
Code:normal error: symbol grub_is_lockdown' not foundI then tried the whole process of restoring grub (https://wiki.manjaro.org/index.php/G...Reinstall_GRUB). I don't get any error messages and all seems fine but on reboot grub again goes into rescue mode with the same error message
Code:error: symbol grub_is_lockdown' not foundI'm using manjaro on stable branch with the newest kernel. Both OSes are installed on the same drive (NVME-SSD). Can you help me? Are there any infos I cna provide you with to help troubleshooting?
