On 2021-11-07 daily-live Kubuntu Jammy Jellyfish INSTALLED without error.

On 2021-11-08 a change had occurred which created bug 1950132.
This change prevents/stops installation at the slideshow stage.

I'm not a programmer or developer but I humbly suggest that a comparison of the changes from the 2021-11-07 version to the 2012-11-08 version might show where the problem lies.

I think this is true for other flavours including Ubuntu itself.

I would do such a comparison myself and deal with it if I knew how but my expertise is very limited..

when it crashed for me twice it was as soon as it tried to use apt, maybe something changed with apt and broke the installer?

@ pqwoerituytrueiwoq

your screen shot shows what happens with this bug
it is what occurred during my attempted install

did you follow through and file a bug report?

I couldn't begin to guess what the problem is

I only know I encounntered it on 2021-11-08
tests before that had completed successfully

I hope someone with the expertise to deal with this comes along

[Norbert (nrbrtx)]

The same "plugininstall.py: ubiquity.install_misc.InstallStepError: AptSetup failed with code 127"

is the reason of the crash.

Latest ISO from Nov. 21.
Booted using grub2's loopmount.
Have to umount /isodevice or it crashes (all older versions were same).
Used manual partitioning to reuse existing old install, changed (tried to) ESP from sda1 to sdb1, but had to umount /sda1 and mount sdb1 as ESP while on screen adding login info.
