Title:
  ubiquity removed package that was installed; is needed later; is known
  to exist remotely; without network

Status in ubiquity package in Ubuntu:
  New

Bug description:
  ubiquity removed package that was installed; is needed later; is known
  to exist remotely; without network

  The 20220809-jammy-desktop-amd64.iso offline install with nvidia;
  installs nvidia-settings in the live session; marks/removes libdpkg-
  perl which nvidia-settings depends on indirectly; then tries to
  install nvidia-settings in target and fails to fetch libdpkg-perl,
  because apt packages lists know about it.

  there are a couple of bugs here:

  - why are security apt lists that are not accessible known to the
  system when trying to do offline in-target nvidia install? (InRelease
  is desired, but Packages is bad)

  - why libdpkg-perl is clearly needed by a package install in-target
  later, is removed from the system before in-target install by
  plugininstall

  I did a backup of the broken iso at
