the grub-efi-amd64-signed package failed to install into /target/ Ubuntu 18.04

I was trying to install Ubuntu 18.04 LTS on my ASUS K55VM Laptop directly into an external HDD and was continuously getting the error during installation “the grub-efi-amd64-signed package failed to install into /target/“.

After searching in google & trying out different options, the only option that worked for me is:

  • In the partition screen, as you create ext4 & swap partitions, ensure to create a 200 MB partition with File System as EFI.

Now, when I tried the installation, it worked without any errors.

Follow the installation steps as mentioned in zachpfeffer’s blog. In addition, as I mentioned, ensure to create EFI partition if you get this error.
