I want to clean up the entries in GRUB on Ubuntu 22.04 since there are a lot of duplicates:

Here's a screenshot of the GRUB menu:

Everything seems to be listed twice.

I already ran apt-get autoremove --purge, but there was nothing to remove. Here's the output of update-grub2:

Can someone tell me where these duplicates come from and how I get rid of them?

I had the same problem and I solved it using Grub-customizer.

I launched grub-customizer and in the list provided (I have 4 Linux distros (debian, ubuntu, mint and elementary), I moved all the main entries to the top and deleted everything else. After reboot the boot menu now shows only my four distros.

To install grub-customizer:

sudo add-apt-repository ppa:trebelnik-stefina/grub-customizer
sudo apt update
sudo apt install grub-customizer
