[Bug 1396506] Re: Ubuntu Server installer does not mount /cdrom for preseeding

[Mathieu Trudel-Lapierre]

This is on purpose. In the installer menu, you also show the use of
"Detect and mount CD-ROM"; the elements of the installer menu are meant
to be run somewhat in the same order as they appear, so on a standard
install, the CD-ROM will be mounted before the preseed file is attempted
to be read.

I've tested this on ubuntu-14.04.1-server-amd64.iso with no issues.

Closing as "incomplete" for now, so please feel free to set it back to
New if you have further details to contribute.

Title:
  Ubuntu Server installer does not mount /cdrom for preseeding

Status in debian-installer package in Ubuntu:
  Incomplete

Bug description:
  When trying to use preseeding, the loading of preseeding file fails
  due to the /cdrom directory not being mounted.

  First when I try to install, no error message is shown and
  installation progresses as normal. However, if I explicitly select the
  menu option "Load debconf preconfiguration file", I am shown the error
  message "Failed to retrieve the preconfiguration file: The file needed
  for preconfiguration could not be retrieved from file:///cdrom/preseed
  /ubuntu-server.seed. The installation will proceed in non-automated
  mode."

  This bug makes it impossible to use any other preconfiguration seed
  file, as the same bug happens with other preconfiguration modes/files.

  A video of reproduction can be found in the attachments.

  If I mount the /cdrom folder manually using "mount -t iso9660 /dev/sr0
  /cdrom", I can load the preconfiguration file correctly.

  This is on ubuntu-14.04-server-amd64.iso, verified by md5 hash and
  integrity verified inside installer as shown in the video.
