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

[Brian Murray]

This doesn't look the same to me - notice the following in the syslog
from comment #37

Apr  3 21:11:11 lubuntu kernel: [ 4058.465844] ubiquity[32493]:

Also the first dmesg posted to this bug contains the following:

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.
