[Bug 1256588] Re: PPC: LiveCD installation window vanishes during installation

[Adam Smith]

You should have a package called python3 according to the manifest.

Does it actually copy the files with the line removed?  Do you see
"Almost finished copying files..."? If you do  then it may be crashing
on the line

self.db.progress('SET', 100)

and we can say the 'set' command is the problem.

If not then it is probably crashing on

self.db.progress(
                                    'INFO', 'ubiquity/install/copying_minute')

You can look at the log to check.

The template files (which store the messages to print) have not changed
for a long time, so it's not them.

Debconf is presumably used by the debian installer and according to your
iso logs that works.

It is hard to understnad how ubiquity and debconf interact.  My hunch is
that it is something before the copying phase that knocks it all out of
sync.  I haven't done programming in years, so it is hard to work out.
I would need to add a load of print messages to the debconf function to
check what it is doing.

Title:
  PPC: LiveCD installation window vanishes during installation

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  I attempted to install from the 20131130 PPC LiveCD via usb flash
  drive. I used the erase entire drive option.

  The installation window proceeds until where the slide show would
  begin. At that point, there is a blank area where the first slide
  would normally be. The progress text reads copying files.

  After about 30 seconds, the entire installation window vanishes, and
  all that is left is the spinning gear. After 90 minutes, the
  installation never finished. I ran ubuntu-bug ubiquity from a
  terminal, and then I did a forced shutdown from the power button on
  the computer. I could not get to a console.

  Examining the hard drive, the installer looks to have partitioned the
  drive, but only installed three folders: /etc., /lost+found, and
  /media.
