[Bug 1926672] Re: ubiquity-gtk installer crashes in focal 20.04.02 after partitioning due to existing EFI partition

Fri May 21 01:07:05 UTC 2021

apport-cli is crashing on hirsute, so I cannot send you the debug log,
but I have tried my setting (with existing swap and efi partitions)
again, and am still getting the same error. I also took some screenshots
and saved the debug log, in case you need it.

Just in case, "apport-cli -u 1926672" and "apport-collect 1926672" are
crashing with the following error:

Title:
  ubiquity-gtk installer crashes in focal 20.04.02 after partitioning
  due to existing EFI partition

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  In focal 20.04.02 the ubiquity-gtk installer (20.04.15.11/focal-
  updates) always crashes after the partition step.

  Although this seems to be an old bug, I could not find a relevant bug
  report so far.

  I am having this issue when installing Ubuntu 20.04 to removable media
  from an existing Ubuntu 20.04 system. I could reproduce the issue on a
  PC in UEFI mode and on another one in BIOS mode. Before reporting this
  bug, I tested the installer on both Live USB media and internal disks.

  How to reproduce?

  1. The install medium needs to be writable (i.e. no CD/DVD) and contain a mounted EFI partition (e.g. /dev/sda1), while the target presumably needs to be a removable medium or a secondary disk.
  2. sudo --preserve-env=DBUS_SESSION_BUS_ADDRESS,XDG_RUNTIME_DIR sh -c 'ubiquity gtk_ui'
  3. In the ubiquity installer create a GPT partition on the target medium (e.g. /dev/sdb) containing an EFI partition (e.g. /dev/sdb1) and a root partition (e.g. /dev/sdb2), and set the Grub target ("boot disk") accordingly.
  4. The installer will ask for confirmation, stating that the partition table of both disks will change and that the two newly created partitions will be formatted. In case of an existing swap partition on the primary disk, this partition will also be formatted (which I consider another bug).
  5. After the crash, you can notice that
     a. the new system has been partially installed, as /target (e.g. /dev/sdb2) is mounted and contains 329 MB
     b. the EFI partition of the install medium or primary disk (e.g. /dev/sda1) has been unmounted from /boot/efi and remounted to /target/boot/efi
     c. the target EFI partition (e.g. /dev/sdb1) has been created and formatted, but is unmounted and empty.

  $ cat /target/etc/fstab
  # /etc/fstab: static file system information.
  #
  # Use 'blkid' to print the universally unique identifier for a
  # device; this may be used with UUID= as a more robust way to name devices
  # that works even if disks are added and removed. See fstab(5).
