Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 grub-efi-amd64-bin : Depends: grub-common (= 2.02-2ubuntu8.21+elementary26~ubuntu5.1.7.1)
 shim-signed : Depends: grub-efi-amd64-signed (>= 1.167~) but 1.93.24+elementary22~ubuntu5.1.7.1+2.02-2ubuntu8.21+elementary26~ubuntu5.1.7.1 is to be installed or
                        grub-efi-arm64-signed (>= 1.167~) but it is not installable
E: Broken packages

I've also tried to install grub-efi-arm64-signed:

$ sudo apt install -f grub-efi-arm64-signed

Package grub-efi-arm64-signed is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'grub-efi-arm64-signed' has no installation candidate

I'm not sure how to verify where that package should be coming from and if it's obsoleted. Below is the output of "apt-get update".

I'm not sure what to do next. In case it matters, my system is multi boot with Windows 10 and I think two intallations of Ubuntu. I can't recall for certain about the Ubuntus, nor the order in which I did things. I think Windows was installed first. Below is my grub menu.

GNU GRUBversion 2.02
*elementary
Advanced options for elementary
Windows Boot Manager (on /dev/sda1)
Ubuntu 20.04.1 LTS (20.04) (on /dev/sdb5)
Advanced options for Ubuntu 20.04.1 LTS (20.04) (on /dev/sdb5)
Ubuntu 20.04.1 LTS(20.04) (on /dev/sdb7)
Advanced options for Ubuntu 20.04.1 LTS (20.04) (on /dev/sdb7)
System setup

Thanks for any help you can provide! Best regards, Mike

  • I have the same issue. Cannot update OS with appcenter (OS elementary 5.1). When I debug the OS update I get this: ** (io.elementary.appcenter:32171): WARNING **: 15:25:26.074: Package.vala:553: Operation failed for package Aktualizacje systemu operacyjnego - WARNING: You are trying to remove the following essential packages: shim-signed grub-efi-amd64-signed (due to shim-signed) I also use WIN10 on the same disk as elementary and I use GRUB

Any thoughts anyone? Would be great even to be pointed to another group/forum to get an answer to this question. I have searched for many hours across the web and cannot get a solid lead on how to proceed. Best I can see is that the shim-signed might be something from Microsoft for secure booting in a dual boot environment, but I cannot find anything specific on how to remedy the situation. This continues to block my OS updates.

Best, Mike

Try to solve this by running:

sudo apt dist-upgrade

If this doesn't help, I usually resolve by using aptitude:

sudo aptitude upgrade

Aptitude is usually smart enough to find proper way out.
