Public bug reported:
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.
