Title:
  error: Running 'grub-install  --force --target x86_64-efi "/dev/sda"'
  failed.

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  Ubiquity 21.04.19 installed via apt on a previous iso daily-build as
  an iso with 21.04.19 at the moment is not available.

  DESCRIPTION:

  - Partition table: msdos (MBR)
  - /dev/sda1 with Ubuntu already installed
  - /dev/sda2 and /dev/sda3 both Ext4

  Installation modality: Install Ubuntu 21.04 alongside...

  As 3 primary partition are already used, the installer is forced to
  use the remaining space creating an extended partition with logical
  partition inside:

  - /dev/sda5 ESP (EFI)
  - /dev/sda6 Ext4 for Ubuntu

  EFI partition should be primary, not logical and as expected a popup:
    Executing 'grub-install /dev/sda' failed 
    This is a fatal error

  Despite this the system get installed and it is bootable.
  Probably because of the recent changes on Ubiquity package.

  Anyway, the 'grub error' message can be tricky!
