@sschapiro: You can test this by using a 16.04 netboot image
(http://cdimage.ubuntu.com/netboot/), and putting apt-
setup/proposed=true on the installer's kernel command line or adding
"d-i apt-setup/proposed boolean true" to your preseed file.  (The result
will be that the installed system has unverified updates on it too, so
it would be best to only use this for testing this fix.)

  invalid sources.list generated from reading apt-

Status in base-installer package in Ubuntu:

Bug description:
  Server users installing with a preseeded local repository.

  [Test case]
  Preseed "apt-setup/local0/repository" for a server install.
  The installation process should complete normally, and the local repository should be enabled on the installed system.

  [Regression Potential]
  This adds support for handling local repositories and configuring them in preseed without adding the "deb" prefix to specify the type of source entry. There is no likely regression type except that of enabling local repositories on installs where the preseed is present and currently seen as invalid by base-installer where the issue was not noticed by systems administrators.


  it looks like configure_apt from library.sh will add the contents of apt-setup/local0/repository verbatim to the sources file. This works only if the repository is prefixed with "deb ", which for apt-setup is optional. Not using a repository prefixed with "deb" will result in an invalid sources.list file.
