Title:
  Ubiquity 21.04.19 ends in 'error install grub' but Ubuntu get
  installed

Status in ubiquity package in Ubuntu:
  New

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

  But EFI partition should be primary, not logical.

  Then grub-install fails.
