After updating to Ubuntu 23.10 the Grub Customizer stopped working and since I have heard bad things about it I decided to just remove it. I tried removing it and cleaning up duplicated menu items on Grub2 and now when I use sudo apt-get upgrade I receive the following error. I am still able to successfully boot into Ubuntu and Windows, but would like to get the error resolved and my bootloader cleaned up. Thanks in advance!

  • /boot/grub/grub.cfg.new says there is a typo some where, so grub-update is not completed. I forgot an closing } in 40_custom and it said error was on last line when actually in the middle. It also can be in /etc/default/grub or any of the scripts that customizer changed. If you have not done much editing of grub, you can just do a total reinstall to grub. You show grub-pc, that is for BIOS based systems, but since 2012 systems have been UEFI with gpt partitioning and grub-efi-amd64. So be sure to reinstall correct version of grub. sudo grub-install if in your install. – oldfred Mar 27 '24 at 14:25
  • Running the grub installer again completes successfully without providing an option to choose a version. I still receive the same error when running apt-get upgrade. – LastBucsfan Mar 27 '24 at 14:45

  • Total reinstall of grub should have replaced everything. But do you still have proxy scripts in /etc/grub.d? This should show details. Please copy & paste the pastebin link to the BootInfo summary report ( do not post report), do not run the auto fix till reviewed. Use often updated ppa version with your USB installer or any working install over somewhat older ISO. https://help.ubuntu.com/community/Boot-Repair & https://sourceforge.net/p/boot-repair/home/Home/ If running Boot-Repair for fix only use Advanced mode and choose total reinstall & new kernel to reset everything. – oldfred Mar 27 '24 at 16:40
  • It's not that these comments are not helpful, but I'm not sure I have the time to go through it properly. Is there way to run the 23.10 upgrade again now that I've removed grub customizer?Or can someone give me a more step by step command to clean this up? – LastBucsfan Mar 27 '24 at 22:12
