  Upgrade Notes:  20 Jun 2008

  Fully upgraded system:
  apt-get update
  apt-get upgrade
  apt-get dist-upgrade
  Using /etc/apt/sources.list:
  deb http://us.archive.ubuntu.com/ubuntu/ dapper main restricted universe multiverse
  deb http://us.archive.ubuntu.com/ubuntu/ dapper-updates main restricted universe multiverse
  deb http://security.ubuntu.com/ubuntu dapper-security main restricted universe multiverse
  deb http://archive.canonical.com/ubuntu dapper-commercial main

  First try using do-release-upgrade failed.

  Removed and reinstalled update-manager and update-manager-core
  apt-get --purge remove update-manager update-manager-core
  The following packages will be REMOVED:
    update-manager* update-manager-core* update-notifier*

  apt-get install update-manager update-manager-core update-notifier

  me at mysys:~$ dpkg -l | grep update-manager
  ii  update-manager         0.42.2ubuntu22.2   GNOME application that manages apt updates
  ii  update-manager-core    0.56~dapper5       manage release upgrades
  me at mysys:~$

  Second upgrade try failed.   Transcript:

  me at mysys:~$ sudo do-release-upgrade

  The 'lsb_release' command also fails.  With the same errors.
  Same results after a re-install of lsb-base and lsb-release.

  Bug research found:
  From: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=341719

  lsb-release tries to deal with the case where /etc/debian_version is
  missing, but doesn't quite manage it.
  https://launchpad.net/distros/ubuntu/+source/lsb-release/+bug/4912 is a
  bug report from an Ubuntu user who thought (incorrectly) that
  /etc/debian_version was a leftover from their previous Debian
  installation and tried to remove it, only to discover that lsb_release
  fell over.
