[Bug 2084032] Re: pc-kernel umount failure

Hello Riccardo63,

I am astonished to receive your mail. I am not Olivier Gayot, neither 
Bug 2084032

I have signaled a bug on my computer with version 24.01, and I am not a 
specialist at all.

*To install the new version, I asked ChatGPT that helped me a lot, 
explaining everything.*

I am not sure the bug I met has been fixed : my bug has been linked to 
another one and I am not sure it is the same.

So I go on with version 22.05 as long as it is maintained. I do not miss 
24.01 version.

Because it caused me a lot of problems : my computer was frozen during 
system loading, before asking me to log in. I had to reinstall 22.05 
version.

Happily, *I had saved all my files before.*

If you have encountered a bug while installing an ubuntu version :

*create 2 root partitions (/) : one for ubuntu 22.05 and one to test 
ubuntu 24.01.*

*and one partition (/home) for the datas
*

as I install ubuntu every two years, I do not remember what I did last 
time. For a standard installation, you have to answer the questions and 
validate each screen. But *it replaces the previous version*, so if 
there still a bug, you will have to reinstall the previous version.

to install on a different partition, it is much more complicated (for 
me). I would have abandonned without the help of ChatGPT : ChatGPT on a 
phone or another computer while installing the new version, you can ask 
what to answer at each question.

Sincerely,

Bug description:
  Doing some install tests with the Oracular October 8 ISO, I had an
  installer crash.

  I booted with a live system and proceed to wipe the internal SSD hard
  disk using `blkdiscard -f /dev/sda` (this disk is quite old, so it's
  recognized as a SATA one, not as a NVME). After that, I completely
  shut down the computer, and booted the Oracular Desktop LiveCD using
  an USB stick created with the October, 8 ISO. I chose "Spanish" and
  "Spanish keyboard", no `accessibility` options, connected to my WiFi
  (no Ethernet available in the laptop), clicked next, next, chose
  `extended selection` to install "all the stuff", clicked next, marked
  both `Install third party software for graphics and WiFi hardware` and
  `Download and install support for additional media formats`, and when
  I press the `Next` button, the installer crashed.

  I attach the contents of the `/var/log` folder.

  I also checked the first 400KBytes of the hard disk, and it's all
  zeros. No data there, as expected after a `blkdiscard`.

  The laptop is an Asus Zenbook UX21E from 2012, with 4GBytes of RAM,
  with an Intel Core i5-2467M CPU.

  The bug can be consistently reproduced after using `blkdiscard`. But
  if the disk has partitions, it doesn't seem to fail.

  I didn't test with other languages. Also, didn't test using `normal
  selection` or not marking `third party drivers` or `additional media
  format`. Only tested that specific combination.

  No FDE/TPM install is being done (the laptop is too old for that).
