[It seems the advise in those documents is outdated and inaccurate.  I
will file some reports on that.]

Synaptic version locking is ineffective in other apt tools.  See bug
#42178.  The same issue exists with aptitude holds.

The only solution is to use apt/dpkg holds, supported everywhere.  The
PinningHowto says to do:
# echo libxfont1 hold | dpkg --set-selections

If your apt is recent enough, you can instead use:
# apt-mark hold harpia shogun-octave

After applying this hold, confirm the changes with e.g.:
$ dpkg -s harpia | grep Status
Status: hold ok installed

Title:
  [update-manager-core] do-release-upgrade removing pinned / locked
  version packages

Status in “apt” package in Ubuntu:

Status in “update-manager-core” package in Ubuntu:

Bug description:
  I want to upgrade Ubuntu, but do-release-upgrade removes even locked-
  version packages. The problem is certain packages, e.g. harpia and
  shogun-octave, no longer exist in recent Ubuntu versions. I need those
  packages. This makes upgrading impossible.

  $ lsb_release -d
  Ubuntu 12.04.2 LTS

  $ do-release-upgrade -d
  raring.tar.gz

  Packages to be removed: [...] harpia shogun-octave

  Packages to be installed: [... harpia and shogun-octave not listed
  ...]

  Packages to be upgraded: [... harpia and shogun-octave not listed ...]

  I think packages with locked versions and their dependencies should be
  left alone during an upgrade.
