stephanomuri1 - Hello

The error is in regards to the grub-efi-amd64-signed package.
See in terminal:

Code:

apt show grub-efi-amd64-signed

I do not recall when the change to Version 2 happened - but I bet it applies in your case.
what shows:

Code:

apt policy grub-efi-amd64-signed

and consider installing the grub-efi-amd64-signed package.

my bit to try and help

Description: GRand Unified Bootloader, version 2 (EFI-AMD64 version, signed)
 GRUB is a portable, powerful bootloader.  This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub.  Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This package contains a version of GRUB built for use with the EFI-AMD64
 architecture, signed with Canonical's UEFI signing key.

i can't reinstall it, I tried other ways from the forums, but it didn't help, still the same errors....

stephanomuri1; Hummm

Package manager do confirm "grub-efi-amd64-signed" is installed.

So, we try and get the package manager to tell us why it is so unhappy.
confirm to us what release we are working with - that the correct versions of packages are installed:

Code:

lsb_release -a

proof to us that all packages are up-2-date

Code:

sudo apt update
sudo apt full-upgrade

And next if all is as spiffy as can be under the circumstances -- we get the package manager to try and tell us what ails it.

gots to be a reason

I reinstalled grub2 via boot repair using live usb and the error did not go away, the packages are still corrupted..

Code:

@: lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 24.04 LTS
Release:    24.04

**Bashing-om** · June 26th, 2024

stephanomuri1; Oh

24.04 and grub issues ...
Just to rule out ( was in my case) a splash hick-up
Boot to grub's boot menu -
e key for edit mode
In this screen arrow down to the "linux" line and remove "quiet splash"
ctl+x to continue the boot.
log in.
Does

Code:

sudo update-grub

now run error free - by some slight chance ?

else next we try and reconfigure the package and see what the system reports.

there's fix somewhere

If the (O)riginal (P)oster does not say; we will never know

-inquiring mind want to know-

**grieda** · June 29th, 2024

I had the same issue with GRUB before. What worked for me was booting from a live USB, mounting my Linux partition, and then reinstalling GRUB from the terminal. Make sure you know which partition your system is on and follow a guide if needed. This fixed the problem for me. Hopefully, it helps you too!

**stephanomuri1** · July 5th, 2024

Unfortunately only a complete reinstallation of linux helped, something was corrupted from the system files, but I'm not too cool user of linux to look for some small bug that caused this, after a complete reinstallation all the errors disappeared related to this).
