[Bug 1010461] Re: Ubuntu 12.04 installer fails on (some) AMD systems with an "unrecoverable error" at start of slideshow

I also get this message:

Problem in ubiquity

The problem cannot be reported:

You have some obsolete package versions installed. Please upgrade the
following packages and check if the problem still occurs:

dmsetup, grub-common, libapt-inst1.4, libapt-pkg4.12,
libdevmapper1.02.1, libgcrypt11, libglib2.0-0, libpolkit-gobject-1-0,
libssl1.0.0, libtasn1-3, libxml2, sudo, upstart

--------------------------------------------

I too am installing on an older AMD machine. As a newcomer to Ubuntu
this is really disappointing. I don't know how to uninstall from a disk,
nor do I know how to deal with obsolete packages. I guess I will put my
tail between my legs and go on home to Windows. It really is too bad,
because I like a lot of what I see of Ubuntu.

Title:
  Ubuntu 12.04 installer fails on (some) AMD systems with an
  "unrecoverable error" at start of slideshow

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  I'm opening this bug report so that the problem discussion and
  solution of the following thread can be found in the bug database:
  http://ubuntuforums.org/showthread.php?t=1966588

  Summary: On quite a lot old AMD platforms the installation process of
  12.04 quits after the screen where you can enter the user information
  and password with the message box

  "Installation failed

  The installer encountered an unrecoverable error. A desktop session
  will now be run so that you may investigate the problem or try
  installing again. "

  The desktop session is started successfully in turn. This message is
  independent on whether the installation program was started from the
  boot manager or from the live system.

  The relevant lines of the syslog are:

  The solution is to uninstall the package ubiquity-slideshow-ubuntu before running the installer with
  sudo apt-get remove ubiquity-slideshow-ubuntu

  
  A related bug seems to be #985066 however as there seem to be two problems reported in one bug report and the title referns to the beta version of the installer (whereas the problem still exists in the final installer) I decided to create a new one.
