[Bug 1889041] Re: bionic daily install to sdc, reboot and UUID not found (grub rescue)

[Chris Guiver]

A re-install of Xubuntu 18.04/bionic daily has completed.

Grub correctly shows (x)ubuntu on sda1, and another Ubuntu on sdc1 (last
install in comment #3 was lubuntu)...

On selecting SDC1/Ubuntu 18.04 I get the error

----
error: no such device: 31c58e86-0f12-4980-ac89-eaa469ca4e80
error: hd2 cannot get C/H/S values.
error: you need to load kernel first.

Press any key to continue.

I've seen that issue before, had it on a QA-test install of 18.04.4, so
it's not new, but it wasn't there during eoan (development) cycle, as it
was the error on the eoan partition (now erased) on SDC, that booted
fine until a RC of 18.04.4 was installed creating that issue. As I
didn't care about eoan it was not a high priority (it'll be recorded on
a qa-test for 18.04.4 if I can find it; this is a duplicate??)

I'm now convinced issue is with `grub2-common` (grub-install), wonder if
there is a wordsize change or something... but I'm guessing...

Title:
  bionic daily install to sdc, reboot and UUID not found (grub rescue)

Status in grub2 package in Ubuntu:
  New
Status in ubiquity package in Ubuntu:
  Invalid

Bug description:
  xubuntu daily (bionic) qa-test install to SDC (full disk)
  on reboot though, system reports UUID isn't found & only grub rescue

  `blkid` reveals
  /dev/sdc1: UUID="72d29572-9844-448c-adda-597d97d1a598" TYPE="ext4" PARTUUID="ec71cd4e-01"
  which is where I installed to, and what it reported (I believe) wasn't found

  please ignore this report until I do more digging, this box isn't used
  except for qa-testing, and I want to ensure I didn't make a mistake.

  (successful test earlier today was to SDA not SDC)

  this system has been rebooted into daily/live for ubuntu-bug, which
  will give me more details to explore I hope.  No ubiquity log as I
  didn't expect issues on reboot.
