Title:
  ubiquity crashed when installing in an external usb drive

Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  The installation happened on a Lenovo T530 (with the internal drive taken out toprevent any damage to it).
  It also involved a 4TB Toshiba portable storage Model DTX140 4TB +5V DC 1.0A, P/N: HDTX140ESCCA FAC:L A

  I tried to install on the external drive. In order to prevent any
  change to my built-in drive, I removed it before booting from the
  Xubuntu 20.04.4 amd64-live stick, which was recognized as /dev/sda.

  Before the installation, I already had created a partition table for
  Xubuntu 20.04 (usual installation with a Linux-Sys partition, a small
  swap partition and a home partition), but I left 4MiB free space
  before the first partition (just to be sure) instead of the 1Mib which
  would normally be used.

  I was unsure, if a Boot partition is really necessary, but for sure I
  also provided one with the recommended size of ca 150MiB.

  Lots of free space were left on the external drive (not et assigned to
  any partition, but to be used later when the disk is actually used).

  It looks like a system has been installed, but to this point I had
  noch chance to test, if the computer really boots from it.

  If needed, I can provide you with screenshots showing all settings
  during the install (it would be nice, if ubiquity automatically could
  report all settings made during an install in order to unambiguously
  document how an installation was made! I would like to provide you
  some more proposals how ubiquity should be improved, some of them will
  be easily implemented but have much impact on usability).

  Please send me an email if you want more information. Unfortunately I
  don't see, if there is any additional information which I might
  extract from logfiles and which might be useful to fix this bug. But I
  know, that my live stick has a partition "writable" and possibly
  (hopefully) other information can be extracted from there, if you
  advise me what to extract.

  By the way: this partition "writable" should be made useful to add
  files, especially *.sh files, in this prtition to be used after
  installation or even: during the boot process in order to improve some
  really bad default settings of the freshly installed system, e.g. a
  colour assigned to "selected text" in a terminal which is in dark
  blue, almost unreadable, or letting me change the default format for
  date in Thunar, in terminal sessions, letting the default columns in
  Thunar be arranged differently (change date first, size second, name,
  access rights, user, group: one often has to sort things by one of the
  first columns in my preferred setting. With the normal order, these
  are somewhere far to the right, so one can not quickly click on the
  header of the thre columns mentioned first).

  Kind regards
