[Bug 1783996] Re: [efi on top of legacy] Show a warning that installation will fail if user doesn't create an ESP partition or fallback to grub-pc

[Launchpad Bug Tracker]

This bug was fixed in the package partman-partitioning - 120ubuntu2

---------------
partman-partitioning (120ubuntu2) cosmic; urgency=medium

  * On EFI systems, make sure there's an ESP partition present regardless of
    whether there's GPT or non-GPT partitions. We need to assume the user is
    unaware of the consequences. (LP: #1783996)
  * Change the wording of the missing ESP partition text to fit more all the
    cases we are trying to handle.

Bug description:
  Test Case:
  1. On a EFI machine with an existing system installed in BIOS mode (without an ESP partition), boot 18.04.1 (in EFI mode)
  2. Select manual partitioning
  3. Resize the main partition
  4. Allocate the free space to Ubuntu and do not create an ESP partition
  5. Proceed with the installation

  Result
  Grub setup and installation fail.

  Given it'll always fail the installer should either display a warning
  (same message than when a new partition table is created in manual
  partitioning mode and an ESP partition is not created) or completely
  forbid the type of setup and prevent the user from confirming the new
  partitioning scheme if he didn't create an ESP partition.
