Dracula theme for grub not working

[RvDekens]

Hello, I try to install Dracula theme for grub but it's not working. I've clone the repo to /home/Documents/temp, copied the dracula folder to /boot/grub/themes and add the line "GRUB_THEME='/boot/grub/themes/dracula/theme.txt" in the grub file (/etc/default/).
I've updated the grub config file using sudo update-grub and got that messages :

Does anyone had this problem ? How can I solve it ?
Thx for your answers

Hi 👋🏻, thank you for your interest in providing this feedback. ✨

But there is a better place to share the same, which is the project repository, where you can talk to the theme maintainers.

✅ Clicking here, you can open an Issue on it.

Ok, thank you.
I've noticed that it's not only the theme Dracula that's not working but any theme I try to use...
I will ask in another forum.
