[Bug 1776115] Re: 18.04 Subiquity install crashes w/ "no such device" aganist /dev/sda2

[Michael Hudson-Doyle]

I think we fixed a bug like this recently but with your description it's
a bit hard to be sure. Can you try the ISO at http://cdimage.ubuntu.com
/ubuntu-server/bionic/daily-live/current/bionic-live-server-amd64.iso
and see if that helps? If it doesn't, can you pastebin the logs in
/var/log/installer from the live session?

Title:
  18.04 Subiquity install crashes w/ "no such device" aganist /dev/sda2

Status in subiquity:
  New
Status in subiquity package in Ubuntu:
  New

Bug description:
  Downloaded "ubuntu-18.04-live-server-amd64.iso" via Windows, burned
  with Etcher onto 2 drives (USB 3.0 and USB 2.0). Installing onto a
  laptop that already had a Debian 9.4.0 install that used the entire
  disk w/LVM managing partitioning, all partitioning per Debian
  defaults.

  With both drives, I start install, get to the Account Creation stage,
  and it throws error around failing to run the "removing previous
  storage devices" and "curtin command block-meta" commands. The Python
  trackback ends with "no such device or address '/dev/sda2'"

  USB drives on this system are clearly working as they not only got
  install to this point, but a rebuild w/the now-alternative installer
  (ubuntu-18.04-server-amd64.iso) succeeds.
