Title:
  fails to install on existing custom ESP of WNX Pro 18.04 GPT/UEFI Dual
  Boot

Status in grub-installer package in Ubuntu:
  New

Bug description:
  Image is Ubuntu Desktop 18.04 LTS
  written to USB 2.0 UFD via Gnome-Disks/Writer in Ubuntu Desktop 16.04.4 LTS


  Custom partitioning

  ESP offset=4MiB size=4512MiB(DVD-5) align=2MiB
  WNX size=23552MiB(23GiB) align=2MiB Ntfs
  LNX size=23552MiB(23GiB) align=2MiB Btrfs

  repeatedly tried with all possible install-targets given in ubiquity (ESP/BIOSBOOT/LNX)
  booted via BIOS/UEFI/CLOVER
  doesn't make a difference if booted direct into ubiquity, or started from live

  manual (grub-pc/grub-efi) install ain't problematic at all under given
  custom conditions

  so i would point pinky to ubiquity, not grub-installer per se

  this was the first time in 7 tries that bug-reporting actually
  proceeded/attempts to handle error automatically before stalled
  ubiquity to total halt/even killing by pid had no effect (as if it
  endlessly respawns immediately trying to start collecting dumps;

  That should be it from here; as i have no idea how to debug in such a
  case and neither am willed to do right now;

  For those that wonder about the alignment and offset; constant
  autocreation of full raw image dumps to udf 2.01 to DVD-SL-5-/BD-
  SL-25- -images, which is speed-up immense, in such a setting; Reason
  for the dumps is not of interest (here).

  System is HP EliteBook 2740P Core-i5 2.53GHz VPro IronLake HD 8GiB
  80GB Intel SSD with AMT/ME enabled and prepared for TXT Boot;
  Virtualization VT-d/EPT(IOMMU) and HyperThreading enabled, to allow
  nested virt boot of non-active os raw-vmdk/partition-boot with host-
  cpu-features shadowed.

  Well, whatever; Feel free to sort it out or not. I'm done with probing
  ubiquity further and go on manually.

  Oh, by the way: the keyboard detection/probing/guessing works as usual
  in subiquity, but ubiquity selects 104-key generic de, instead given
  105-key de-nodeadkeys.
