[Bug 1924823] Re: ESP on install medium automatically configured as ESP for install, failing install

[Jeremie Tamburini]

Some more info:

- I repeated the installation selecting the "don't use this partition" option for the EFI partition of the USB device.
The result is still the same like in the example of guiverc:
/dev/sda1 on /target type ext4
/dev/sdb2 on /target/boot/efi

- I filed a new bug report: bug #1924856
I thought it might be useful to have some data when installation succeed using one of the automatic option. In this case I've selected "Install Ubuntu alongside other system".
An ESR partition is automatically created on /dev/sda3.

Till Ubuntu 20.04 everything was fine. There still were two different modality to boot the USB/dvd device: "uefi modality" and "old bios modality".
All these issues started with Ubuntu 20.10 where the way to boot the USB/dvd device is now unified.

Title:
  ESP on install medium automatically configured as ESP for install,
  failing install

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  This bug report is a duplicated of bug #1902269 performed with Ubuntu 20.10.
  Basically installation fail when the installer doesn't find an EFI (ESR) partition on computers with legacy BIOS.

  This time I have used Ubuntu 21.04 also to test the new version of
  Ubiquity package (21.04.15) which, as reported here:
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1893964/comments/22
  should have fixed the issue.

  Unfortunately I'm still experiencing the same problem.

  #### Partition details:
  - msdos partition table
  - 4 primary partitions, all ext4
