[Bug 1951399] Re: Budgie, Kubuntu, Kylin, MATE, Xubuntu: jammy daily fails to install

[Bob H]

Ubuntu Desktop amd64 fails to install on my system. Throws up 'Installer
Crashed' error message during slideshow.

Manual partitioned install to solid state drive, nvidia so using safe
graphics and third party software,

This problem first appeared in Jammy Jellyfish on 08-11-2021.

Before that date all was working fine. Daily checks had proceeded with
no problems.

Again I humbly suggest some change was introduced between 07-11-2021 and
08-11-2021 and is the cause of this problem.

Title:
  Ubuntu,Budgie, Kubuntu, Kylin, MATE, Xubuntu: jammy daily fails to
  install

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  Ubiquity crashes when user tries to run ISO QA testing by following
  the procedure from:

  http://iso.qa.ubuntu.com/qatracker/testcases/1300/info
  http://iso.qa.ubuntu.com/qatracker/testcases/1305/info

  The actual result is the same: installer crashes with the following last line in the small terminal at the bottom - "plugininstall.py: ubiquity.install_misc.InstallStepError: AptSetup failed with code 127" .
  Does not depend on system type - happens on real hardware, QEMU, Virtualbox.

  
  This plugininstall.py came from ubiquity package.

  Expected result is completed bootable installation.
