Xubuntu 23.10 "Mantic Minotaur" - Daily amd64 (20230829)

I'm on my primary box now (dell optiplex 7050) which uses Secure-uEFI
boot, and this install was last made after a problem during the mantic
cycle that caused 2 of my 5 screens to go dark (be it installed system
or LIVE boots). When the live boots no longer had an issue, but it had
remained on my installed system & I was unable to work out why; I just
non-destructively re-installed the system as fix.

FYI:  This system is a single-partition install (plus ESP), being
installed using a testcase that didn't create a separate /home.  Xubuntu
used `ubiquity` when I re-installed using daily 2023-08-29, ie. fix my
issue & a QA install.

Whilst I sometimes disable secure-boot (virtualbox is easier) the
machine is still uEFI & I use it regularly there in QA too (mostly
Xubuntu, with calamares).


Personally I'd prefer the boot as 'non-ideal' as the passwd/sudo issue can be easily resolved & just documentation suggesting FORMAT is used.  The loss of this re-install feature (something I've always loved about Ubuntu, and regularly use) would be a large loss, esp. on a LTS release.

  User account is missing from /etc/shadow & /etc/passwd

Bug description:
  This has been attempted a number of times, using various ISOs, after
  each time I'm unable to login on booting the newly installed xubuntu
  noble system.

  install to 
  - hp dc7700 (c2d-e6230, 7gb, amd/ati rv610/radeon hd2400 pro/xt)

  to re-create I

  - boot current daily
  - select manual partitioning
  - re-use the '/' partition (80GB drive & single partition), NO FORMAT
  - install (options here don't matter, eg. full install, select to add additional options usually, I have internet connected)
  - username is "guiverc" and my password is "please" each time  (I ignore warning about 'WEAK' password)

  install completes, I then reboot

  ** expected outcome

  System boots; DM asks me to login saying "Other"   (I expected
  'guiverc' and only to enter my password; but okay)..

  On entry of my username "guiverc" & password "please" I expect to
  login

  ** actual outcome

  I enter username "guiverc" and password "please" but I cannot login

  I switch to text terminal, and "guiverc" & "password" aren't accepted
  there either.

  ** additional notes.

  I've tried this with ENGLISH(US) and ENGLISH(AU) (aussie) and same
  result for both.

  Machine is really old BIOS only box.

  If I FORMAT instead of NO-FORMAT I don't have this problem though.. It
  appears to occur only when I don't format (and I don't want to format
  for this type of install!)
