Installation fails

[Hans-Petter Falao]

All seems normal until nearly finished. I have downloaded fresh every night; still fails the same way after more than one week.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm having to override installation failure termination and continue without grub install. In order to recover this effort, I perform LiveUSB boot of Ubuntu Desktop 23.04 and perform boot-repair installation and forced repair of the incomplete installation.

Besides the Bootloader installation failure, there is a secondary issue of backleveled kernel.
From original problem report: Uname: Linux 6.2.0-1003-lowlatency x86_64

As of this post for comparison:
uname -r results for Live Server 23.10 Daily and Kubuntu 23.10 Daily reports: 6.3.0-7-generic

Once I get grub installed on /dev/sda in order to boot the installed image, I then have to obtain a more current kernel including the Non-Lowlatency version.
