Although older versions of those packages are installed, the
updated mysql-server states that it requires the more recent
versions, as indicated by the error:

 mysql-server-5.5: PreDepends: mysql-common (>=
5.5.24-0ubuntu0.12.04.1) mais la version 5.5.28-0ubuntu0.12.04.2 est
installée
                   Depends: mysql-client-5.5 (>=
5.5.24-0ubuntu0.12.04.1) mais la version 5.5.28-0ubuntu0.12.04.2 est
installée

The newer packages downloaded (you see them in /var/cache/apt), but
failed to install, presumably due to the disk space error.

The dpkg command is unsafe is because it ignores the package
dependencies.  The program may actually run with the older packages,
and there may not even be any problems, but this can generally not be
assumed, otherwise it would not require particular versions of those
packages.

I am glad that you fixed your system.

The only issue here really is that apt proceeded with the operation
even though it would fail due to disk space.  I believe this is
already reported, and the situation is unlikely to improve much
because this is something very hard for apt to *properly* check.

Generally, it is up to the system administrator to keep disk space
issues under control.  Software can not reliably do this for you.

The first part uses the packaging dependency format as this is the
best way to convey exactly which dependency causes the problem, and
what it's requirements are.  Although not the most correct for natural
language, it does read well enough, and changing it is undesirable
because that may lead to ambiguity and make the task of diagnosing
problems (for packagers, developers, people familiar with that syntax)
a bit slower.

Title:
  error after running out of disk

Status in “apt” package in Ubuntu:
  New

Bug description:
  After i ran out of disk space I get this error after a daily update
  (I run a french ubuntu 12.04 so the following messages are in French but translation would be  "mais la version x est installée" = "but the x version is installed")

  Les paquets suivants ont des dépendances non-satisfaites :

  I don't understand what is wrong. 
  There's enough disk space right now (6gb)
  I "fixed" this by using dpkg --force-depends -i mysql-server_5.5.28-0ubuntu0.12.04.2_all.deb

  In cache I got the following files
  libmysqlclient18_5.5.28-0ubuntu0.12.04.2_amd64.deb
