Unable to update system package grub-efi-amd64-signed [SOLVED]

[josefg]

Hi,

I just did a clean install on a new laptop, by installing Linux Mint 19 Main Edition, Cinnamon, and then upgrading it to Mint 19.2. Then, I wanted to apply all pending system updates, but I am coming across a problem with the package grub-efi-amd64-signed. Here is my output from the terminal:

Code: Select all

myuser@pc:~$ sudo dpkg --configure -a
[sudo] password for myuser:          
Setting up grub-efi-amd64 (2.02-2ubuntu8.13) ...
dpkg: error processing package grub-efi-amd64 (--configure):
 installed grub-efi-amd64 package post-installation script subprocess returned error exit status 255
dpkg: dependency problems prevent configuration of grub-efi-amd64-signed:
 grub-efi-amd64-signed depends on grub-efi-amd64 | grub-pc; however:
  Package grub-efi-amd64 is not configured yet.
  Package grub-pc is not installed.

dpkg: error processing package grub-efi-amd64-signed (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 grub-efi-amd64
 grub-efi-amd64-signed

I also tried the following:

Code: Select all

myuser@pc:~$ sudo dpkg --configure grub-efi-amd64
[sudo] password for myuser:          
Setting up grub-efi-amd64 (2.02-2ubuntu8.13) ...
dpkg: error processing package grub-efi-amd64 (--configure):
 installed grub-efi-amd64 package post-installation script subprocess returned error exit status 255
Errors were encountered while processing:
 grub-efi-amd64

Any advice available?

Thanks in advance.

Try going to the update manager and click edit>software sources>maintenance>click on the first 3 in the list one at a time. Then try refreshing the updates.

Thanks for the advice. I did so, and then ran the updates from the terminal (sudo mintupdate-cli upgrade), and it worked!
