How do I install Grub Customizer on Ubuntu 20.04? [duplicate]

I'm trying to install grub-customizer on Ubuntu 20.04 and it's not working.

This is what I've tried (as suggested by multiple websites):

$ sudo add-apt-repository ppa:danielrichter2007/grub-customizer
$ sudo apt update
$ sudo apt install grub-customizer

It doesn't seem to find the package:

Err:13 focal Release 404 Not Found [IP: 91.189.95.83 80]

This is the output from the last command:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package grub-customizer

I've read in a few places that people have been able to install this on 20.04 correctly. What am I doing wrong?

Thanks

What happens is the ppa doesn't support Ubuntu Focal, so you need to remove the external first.

sudo add-apt-repository --remove ppa:danielrichter2007/grub-customizer
sudo apt update

The good news is, grub-customizer exist on default repository.

sudo apt install grub-customizer
