[Bug 1939370] [NEW] update-grub is not detecting prior QA-test install (likely b/c BTRFS)

Tue Aug 10 05:55:07 UTC 2021

Public bug reported:

lubuntu 20.04.3 QA-test install on
- hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)

** Summary

update-grub is not detecting prior QA-test install; grub is only
offering new install as boot option

Two installs were performed on this box
(1) Manual partition; two partitions / (btrfs) & /home (ext4)
(2) Install alongside; the /home was selected to be split

** Expected Results

I expect a new install to show two choices in grub
- (L)ubuntu 20.04.3 (first install)
- (L)ubuntu 20.04.3 (this new install which was an 'install alongside'

** Actual Results

First login (of new install) and I ran `sudo update-grub` (after copying
first grub.cfg to grub.cfg.org) and `diff` shows only

guiverc at dc7700:/boot/grub$ diff grub.cfg grub.cfg.org
103c103
<   set lang=en_AU
---
>   set lang=C

so one first boot into new system, I get the same result as it did
during install.  (the `diff` results could be common, or a result of me
not having the ethernet cable in box at time calamares was started for
first install; prior install was no-internet so cable had been removed)

Using `pcmanfm-qt` to mount partitions and re-run `update-grub` & `diff`
with & same answers.

** Likely Cause

The prior install was a BRTFS "/" partition which is likely cause.  It
likely won't impact many users, in fact when navigating there in
`pcmanfm-qt` I get a "@" directory before I see the actual real "/"
