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

[Adam Smith]

Hmm... I have no way of testing this.  Not until just before the release
date which will be too late.  Looking online at the code it is hard to
see what the problem is.  The offending files don't seem to have changed
for a long time.  Is this a ubiquity bug, or a debconf bug, or has
something changed in python3 revealing an endian issue with strings????

>From your ubiquitysyslog the error is being generated when the progress
bar is being set.  You could try commenting out one of the offending
lines.  For example, before you run ubiquity, open
/usr/share/ubiquity/install.py and comment out (put a # before it) the
line

self.db.progress('SET', 10 + copy_progress)

Run ubiquity and see if it works.  It may then fail on another
self.db.progress line.

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.
