Title:
  Ubiquity crash while installing Jammy MATE

Status in ubiquity package in Ubuntu:
  New

Bug description:
  I was trying to install today's daily build of Ubuntu MATE 22.04, and
  a bit after the "user account data" page, ubiquity crashed.

  UbiquitySyslog.txt shows that the problem is that
  /target/etc/apt/sources.list is missing, and a `grep` command fails
  the installation:

  """
  Nov 20 08:35:18 ubuntu-mate ubiquity: grep: /target/etc/apt/sources.list
  Nov 20 08:35:18 ubuntu-mate ubiquity: : No such file or directory
  ...
  ubiquity.install_misc.InstallStepError: AptSetup failed with code 127
