[Bug 1924205] Re: lubuntu hirsute QA-test install & prior ubuntu system fails to boot

[Chris Guiver]

POSSIBLE CAUSE :

I booted into Ubuntu hirsute (sda1) system again..

it's `fstab` refers to 
/sda1 for / referenced by UUID
/boot/efi which is referenced by UUID & comment reports it as /dev/sdb2

so did the system boot ONLY because I had a thumb-drive plugged in
during my pre QA-install tests ??

The original Ubuntu thumb-drive (K) did still contain the Ubuntu daily
image at the time I did my pre-QA checks...

As Lubuntu has grown (just today) to beyond what I my usual 2GB forza-
thumb-drive can handle; I had to re-write it to a larger one and used
thumb-drive-K so the original media is now a different image.. and maybe
this bug is just a result in my forgetting to ensure USB ports were
empty..

I would have checked USB ports during the prior QA-test of Ubuntu
hirsute on the prior install; but may have re-inserted drive when box
was turned off so thumb-drive was easy to find for today's tests..

Title:
  lubuntu hirsute QA-test install & prior ubuntu system fails to boot

Status in ubiquity package in Ubuntu:
  New

Bug description:
  Lubuntu hirsute (daily) QA-test install on
  - hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

  Testcase: install alongside

  Note:  Lubuntu should be using the `calamares` installed, but due to
  https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1923881 the
  current ISO is using `ubiquity` instead

  Prior to install there was one partition (sda1) which contained Ubuntu
  hirsute  (a prior QA-test install).

  It was tested & booted normally prior to this QA-test

  ** expected result

  Post-Lubuntu install; I have two systems

  - ubuntu hirsute (boots & operates as it did prior to this QA-test install)
  - lubuntu hirsute install

  Both available via grub

  ** actual result

  - ubuntu fails to boot; recovery console only
  - lubuntu install works perfectly.

  ** changes noticed

  From a single partition (sda1 using all disk space) I now have

  sda1 ext4
  sda2 fat32 /boot/efi in lubuntu
  sda3 extended
  sda5 ext4 / for lubuntu

  I wonder if the addition of the fat32 has altered the booting of
  ubuntu hirsute.

  
  I'd really like to search the iso.qa.ubu test results & find my last ubuntu hirsute install to confirm how I recorded the tests....   When I booted ubuntu; I expected it to fail to boot (been having loads of failures lately with Ubuntu hirsute on BIOS boxes) but it booted correctly, looked good so I expected the same post this install...  I'm wondering if the successful boot was just a fluke (but that's likely worse!)

  
  This whole bug report maybe pointless due to aforementioned Lubuntu using `ubiquity` to install issue..  but I've reported in case it shows an issue with Ubuntu ubiquity (and BIOS/non-EFI install where ESP partition is added) on pre-EFI boxes, and I need a bug report to fail the iso.qa.ubuntu.com result..
